Accessing user-defined fields added via an extension in Acumatica - acumatica

I have a custom field called 'UsrIsTeacherBook` which was added to the InventoryItem with the following extension:
namespace Lasalle.TeacherBooks
{
public class InventoryItem_TeacherBooks_Extension : PXCacheExtension<InventoryItem>
{
[PXDBBool]
[PXUIField(DisplayName = "Is Teacher Book")]
public virtual bool? UsrIsTeacherBook { get; set; }
public abstract class usrIsTeacherBook : IBqlField { }
}
}
I need to be able to access the value of this IsTeacherBook field from the SOLine grid on the SalesOrder screen. I added a custom field UsrTeacherBook to the SOLine grid on the sales order screen, but I cannot figure out how to populate this field with the value of InventoryItem UsrIsTeacherBook.
I tried customizing the attributes on the SOLine field in the following way:
[PXDBBool]
[PXUIField(DisplayName="Teacher Manual", Visible = true, Enabled = false)]
[PXFormula(typeof(Selector<SOLine.inventoryID, InventoryItemExt.usrIsTeacherBook>))]
But this produced a validation error, "The type name 'usrIsTeacherBook' does not exist in the type 'PX.Objects.IN.InventoryItemExt'."
What is the correct way to access the InventoryItem IsTeacherBook field to populate my field on the SOLine grid?

Your extension class name is InventoryItem_TeacherBooks_Extension, not InventoryItemExt used in PXFormulaAttribute. You should either change your extension name to InventoryItemExt or modify PXFormula declaration with InventoryItem_TeacherBooks_Extension.usrIsTeacherBook

PXSelector attribute suppress Error on form

Good day
I have created a custom Location field for warehouse locations:
#region UsrTOLocation
[PXString]
[PXUIField(DisplayName = "To Location")]
[PXSelector(typeof(Search<
INLocation.locationCD,
Where<INLocation.siteID, Equal<Current<INRegister.toSiteID>>>>))]
public virtual string UsrTOLocation { get; set; }
public abstract class usrTOLocation : PX.Data.BQL.BqlString.Field<usrTOLocation> { }
#endregion
When the location does not exist I create it using code in a button.
Since I have added the PXSelector to the above field I keep getting an error when it doesn't find the locations. This is correct because I still need to create it
Is there a way to suppress the error that it is not finding the location?
You can use ValidateValue property of the PXSelector attribute.
For instance:
[PXSelector(..., ValidateValue = false)]
It disables validation and therefore error appearing in PXSelector attribute

Show unbound field with PXFormula

I'm trying to show a value calculated with PXFormula but the field doesn't show the value.
I have my CustomDAC named EDITran
public class EDITran : IBqlTable
{
#region Doctype
[PXDBString(50, IsKey = true, IsUnicode = true, InputMask = "")]
[PXUIField(DisplayName = "Doctype")]
[PXStringList
(new string[]
{"SO", "SHI", "INV" },
new string[]
{"Sales Order", "Shipment", "Invoice"}
)]
public virtual string Doctype { get; set; }
public abstract class doctype : PX.Data.BQL.BqlString.Field<doctype> { }
#endregion
#region Erprefnbr
[PXDBString(30, IsKey = true, IsUnicode = true, InputMask = "")]
[PXUIField(DisplayName = "ERP RefNbr")]
public virtual string Erprefnbr { get; set; }
public abstract class erprefnbr : PX.Data.BQL.BqlString.Field<erprefnbr> { }
#endregion
#region Sync
[PXDBBool()]
[PXUIField(DisplayName = "Sync")]
public virtual bool? Sync { get; set; }
public abstract class sync : PX.Data.BQL.BqlBool.Field<sync> { }
#endregion
}
}
so I what to show the value of sync field on the Sales Order screen. The key is the ERP RefNbr (which would be SOOrder.OrderNbr)
I have added the custom non persisted field on the SOOrderExt DAC with this attributes
using PX.Objects.SO;
[PXBool]
[PXUIField(DisplayName="EDI Sync" , Enabled = false)]
[PXFormula(typeof(Selector<SOOrder.orderNbr,
Selector<EDITran.erprefnbr,
EDITran.sync>>))]
But when I added a record in EDITran and try to visualize it in SOOrder Form and I checked that EDITran.Sync = 1, it doesn't show the saved value.
Sales Order Screen
What I'm I doing wrong? Is the PXFormula correctly used?
PXFormula used incorrectly. PXFormula attribute works only with current DAC (which is SOOrder) or foreign DAC, existing in PXSelector join condition (you can use Selector keyword to get it).
For example, here is the SOOrder.OrderNbr selector declaration
[SO.RefNbr(typeof(Search2<SOOrder.orderNbr,
LeftJoinSingleTable<Customer, On<SOOrder.customerID, Equal<Customer.bAccountID>,
And<Where<Match<Customer, Current<AccessInfo.userName>>>>>>,
Where<SOOrder.orderType, Equal<Optional<SOOrder.orderType>>,
And<Where<Customer.bAccountID, IsNotNull,
Or<Exists<Select<SOOrderType,
Where<SOOrderType.orderType, Equal<SOOrder.orderType>,
And<SOOrderType.aRDocType, Equal<ARDocType.noUpdate>,
And<SOOrderType.behavior, Equal<SOBehavior.sO>>>>>>>>>>,
OrderBy<Desc<SOOrder.orderNbr>>>), Filterable = true)]
public virtual String OrderNbr
you can get some fields from the related Customer record, using Selector keyword
[PXFormula(typeof(Selector<
SOOrder.orderNbr,
Customer.consolidateStatements>))]
As a result, there are two possible solutions:
1) Rewrite SOOrder.OrderNbr selector declaration with your EDITran DAC
...
[SO.RefNbr(typeof(Search2<SOOrder.orderNbr,
LeftJoinSingleTable<Customer, On<SOOrder.customerID, Equal<Customer.bAccountID>,
And<Where<Match<Customer, Current<AccessInfo.userName>>>>>,
LeftJoin<EDITran, On<EDITran.doctype, Equal<SOOrder.orderType>,
And<EDITran.erprefnbr, Equal<SOOrder.orderNbr>>>>>,
Where<SOOrder.orderType, Equal<Optional<SOOrder.orderType>>,
And<Where<Customer.bAccountID, IsNotNull,
Or<Exists<Select<SOOrderType,
Where<SOOrderType.orderType, Equal<SOOrder.orderType>,
And<SOOrderType.aRDocType, Equal<ARDocType.noUpdate>,
And<SOOrderType.behavior, Equal<SOBehavior.sO>>>>>>>>>>,
OrderBy<Desc<SOOrder.orderNbr>>>), Filterable = true)]
public virtual String OrderNbr
Then it will be possible to get you field from there
[PXFormula(typeof(Selector<
SOOrder.orderNbr,
EDITran.sync>))]
2) Use PXDBScalar attribute to just get what you need. Note this will be a separate request to the database!!
...
[PXBool]
[PXDBScalar(typeof(Search<EDITran.sync,
Where<EDITran.doctype, Equal<SOOrder.orderType>,
And<EDITran.erprefnbr, Equal<SOOrder.orderNbr>>>>))]
public virtual bool? Sync
I'm not sure that's the right use of PXFormula. Here's the reference I normally use when I need to use PXFormula. See if it helps you simplify your PXFormula. You may need to simplify to a single Selector and define a foreign key to be able to complete your lookup.
Also, are you sure that the database contains the values that you expect? I often find that my problem is not where I think, and your issue may lie in setting the values or writing them to the database in your business logic.
It appears that you need the PXFormula to look to your EDITran table to find the record identified by the key (1st field specified in Selector) to then return back the value of the second field specified, which would reside in EDITran.
From Acumatica Developers Blog (AsiaBlog):
Selector
Selector does following:
Fetches a PXSelectorAttribute defined on the foreign key field (KeyField) of the current DAC.
Fetches the foreign data record currently referenced by the selector.
Using calculates and returns an expression on that data record as defined by ForeignOperand.
public class APVendorPrice : IBqlTable
{
// Inventory attribute is an aggregate containing a PXSelectorAttribute
// inside, which is also valid for Selector<>.
[Inventory(DisplayName = "Inventory ID")]
public virtual int? InventoryID
[PXFormula(typeof(Selector<
APVendorPrice.inventoryID,
InventoryItem.purchaseUnit>))]
public virtual string UOM { get; set; }
}
From that, I'd expect your PXFormula to look more like:
[PXFormula(typeof(Selector<
SOOrder.orderNbr,
EDITran.sync>))]
... assuming you have enough defined to tell Acumatica how to relate SOOrder.orderNbr to EDITran.erprefnbr.

Custom field with InventoryAttribute and PXRestrictor based on ItemClass no longer working in 2018R1

We have a custom field with a lookup/selector for Inventory Item that I had restricted to only a certain item class. With 2018R1, the ItemClassID field is now an int and I need to compare to the ItemClassCD field.
My PXRestrictor can only access fields from the original DAC. How best should I rewrite this to accommodate the change to the item class?
#region ParentInventoryID
[Inventory( IsKey = true, Visibility = PXUIVisibility.SelectorVisible, DisplayName = "Parent Inventory ID")]
[PXRestrictor(typeof(Where<InventoryItem.itemClassID, Equal<ItemClass.cabledTransceiverFinishedProduct>>), "Parent is not a cabled transceiver finished product.")]
[PXDefault()]
[PX.Data.EP.PXFieldDescription]
[PXParent(typeof(Select<InventoryItem, Where<InventoryItem.inventoryID, Equal<Current<parentInventoryID>>>>))]
public Int32? ParentInventoryID { get; set; }
public abstract class parentInventoryID : IBqlField { }
#endregion
A new table INItemClass has been created to store the Inventory Item Class.
InventoryItem.INItemClassID key field points to a INItemClass record.
I think that the Inventory attribute doesn't join the INItemClass by default so you would have to add that join in the attribute type parameter.
With the INItemClass join you can restrict on the text field INItemClass.itemClassCD:
[Inventory(typeof(Search2<InventoryItem.inventoryID,
InnerJoin<INItemClass, On<INItemClass.itemClassID, Equal<InventoryItem.itemClassID>>>>),
typeof(InventoryItem.inventoryCD),
typeof(InventoryItem.descr),
DisplayName = "Parent Inventory ID")]
[PXRestrictor(typeof(Where<INItemClass.itemClassCD, Equal<ItemClass.cabledTransceiverFinishedProduct>>), "Parent is not a cabled transceiver finished product.")]

How to change the Display Name for one of the PXSelector fields

I need to change the Display Name to "Primary Vendor" for a BAccount.acctName field, which is the last field to display in the PXSelector that I have created.
I have tried creating an field Extension which does the trick, but this option also renames the field for another inquiry page, therefore I cannot use it.
The following is my code:
Selector
[PXNonInstantiatedExtension]
public class SO_SOLine_ExistingColumn :
PXCacheExtension<PX.Objects.SO.SOLine>
{
#region InventoryID
[PXMergeAttributes(Method =
MergeMethod.Append)]
[PXSelector(typeof(Search2<InventoryItem.inventoryCD,
LeftJoin<BAccount, On<BAccount.bAccountID,
Equal<InventoryItem.preferredVendorID>>>,
Where<InventoryItem.descr, IsNotNull>>),
typeof(InventoryItem.inventoryID),
typeof(InventoryItem.inventoryCD),
typeof(InventoryItem.descr),
typeof(InventoryItem.postClassID),
typeof(InventoryItem.itemStatus),
typeof(InventoryItem.itemType),
typeof(InventoryItem.baseUnit),
typeof(InventoryItem.salesUnit),
typeof(InventoryItem.purchaseUnit),
typeof(InventoryItem.basePrice),
typeof(BAccount.acctName), ValidateValue = false) ]
public int? InventoryID { get; set; }
#endregion
}
Field Extension
public class BAccountExt : PXCacheExtension<PX.Objects.CR.BAccount>
{
#region UsrCustomField
[PXDBString(250, IsUnicode = true, BqlField =
typeof(BAccountR.acctName))]
[PXUIField(DisplayName = "Primary Vendor")]
public virtual string AcctName { get; set; }
public abstract class acctName : IBqlField
{
}
#endregion
}
As you found out the cache extension modifications applies to all screens who use that DAC. There is another extension mechanism applied on a per graph basis called CacheAttached that is applied after the cache extension.
To use it first you need to identify the graph of the screen you want to customize and the DAC field you want to modify. You can use the inspect element feature for this. In this example the graph for Customers screen is 'CustomerMaint' and the DAC field is 'Customer.acctName':
Once you have that information you can create an extension for that graph and extend the DAC field inside it. DAC field extensions defined in the graph using the CacheAttached method will only apply to screens who uses that graph:
public class CustomerMaint_Extension : PXGraphExtension<CustomerMaint>
{
[PXMergeAttributes(Method = MergeMethod.Merge)]
[PXUIField(DisplayName = "Display Name For Customers Graph")]
public virtual void Customer_AcctName_CacheAttached(PXCache sender)
{
}
}
The prototype convention for CacheAttached extensions is:
void DAC_DACField_CacheAttached(PXCache sender) { }
You change DAC and DACField to the field you are targeting. Method definition (body) should remain empty. The attributes decorating the CacheAttached method will apply to the field you're customizing. With attribute PXMerge you can tweak how the CacheAttached extension is applied, it allows to merge the field new attributes of the extension with the base one or completely replace the base attributes.
For more details look at this blog post:
http://asiablog.acumatica.com/2017/01/append-and-replace-of-dacs-attributes.html
you can also try like below but this is limited to the specific graph.
public class CustomerMaint_Extension : PXGraphExtension<CustomerMaint>
{
public override void Initialize()
{
PXUIFieldAttribute.SetDisplayName<Customer.acctName>(Base.BAccount.Cache, "Primary Vendor");
}
}

PXDBCalced - how to invoke

I have a custom DAC in which I have an unbound field on which I've applied a PXDBCalced attribute. I used PXDBCalced because I'm using two other fields that are on the DAC row. Here's how I have the field defined:
public abstract class margin : PX.Data.IBqlField
{
}
[PXDecimal(2)]
[PXDBCalced(typeof(Sub<IsNull<CFSVCProfile.revenueBudget,CFHelper.decimal_0>,
CFSVCProfile.costBudget>), typeof(Decimal))]
[PXDefault(TypeCode.Decimal, "0.0")]
[PXUIField(DisplayName = "Margin", Enabled = false)]
public virtual decimal? Margin { get; set; }
The problem I am having is that the field that has the PXDBCalced attribute is not getting updated when I update the row in the DAC. So, how do I get the calculation to run and update the field?
Thanks!
I would try PXFormula or PXUnboundFormula on your field as its not necessary to hit the database with PXDBCalced based on your example.
[PXUnboundFormula(typeof(Sub<IsNull<CFSVCProfile.revenueBudget,CFHelper.decimal_0>,
CFSVCProfile.costBudget>))]
