Why is it necessary sometimes to copy an instance into a variable, update the variable and then update the instance with the variable ?
protected virtual void INRegister_ToSiteID_FieldUpdated(PXCache sender, PXFieldUpdatedEventArgs e)
{
if(e.Row != null)
{
foreach (INTran item in this.transactions.Select())
{
INTran updated = (INTran)this.transactions.Cache.CreateCopy(item);
updated.ToSiteID = ((INRegister)e.Row).ToSiteID;
this.transactions.Cache.Update(updated);
}
}
Set1Step((INRegister)e.Row);
}
Why can't we update the property itself directly, e.g. item.ToSiteID ? Is it because it prevents firing an event or something ?
Using CreateCopy method in order to update a DAC field was required before version 5.x. As of right now, there is absolutely no reason to create a copy of a DAC record unless you intentionally want to copy all field values from one DAC record to another.

I am trying to enable the custom field in Case when the Status is in Closed State. I am working on a customization for Acumatica version 20.114.0020 (2020 R1).
I have created a custom field usrIsNotBillable in CRCase DAC.
[PXDBBool]
[PXUIField(DisplayName="Confirmed Not Billable", Enabled = true)]
public virtual bool? UsrIsNotBillable { get; set; }
public abstract class usrIsNotBillable : PX.Data.BQL.BqlBool.Field<usrIsNotBillable> { }
It is totally working fine when the Case is in other states than Closed. But when the case is closed, every other property gets disabled. But I want this field to be set enabled. So, I override the Row Selected method for CRCaseMaint graph as below:
protected void CRCase_RowSelected(PXCache cache, PXRowSelectedEventArgs e, PXRowSelected InvokeBaseHandler)
{
InvokeBaseHandler?.Invoke(cache, e);
CRCase row = (CRCase) e.Row;
if (row == null) return;
Base.CaseCurrent.Cache.AllowUpdate = true;
Base.CaseCurrent.AllowUpdate = true;
PXUIFieldAttribute.SetEnabled<CRCaseExt.usrIsNotBillable>(cache, row, true);
}
If I use other DAC fields such as IsBillable like this:
PXUIFieldAttribute.SetEnabled<CRCase.isBillable>(cache, row, true);
It just works fine.
I checked other examples too and the implementation is similar to this. I am just not sure why it is not working in this case.
I have also checked if this screen has any existing workflows and it doesn't.
Any help would be appreciated.
Thanks.
Besides writing code to enable the field in RowSelected event, it is also important to add the field in Closed state in the Workflow.
However, if this is also not working deleting contents of CstDesigner of project does the job.
I'm customizing the Sales Order screen as follows:
I've added a custom boolean field added to the Order Types screen called 'Require Customer Order Number'.
I've added code to the BLC of the Sales Order screen where I want to conditionally make the CustomerOrderNumber field required, based on whether the 'Require Customer Order Number' field is checked or not.
I'm using the SOOrder_RowSelected event as follows:
protected virtual void SOOrder_RowSelected(PXCache sender, PXRowSelectedEventArgs e)
{
var soorder = (SOOrder)e.Row;
if (soorder == null) return;
string ordtype = soorder.OrderType;
var soot = (SOOrderType)PXSelect<SOOrderType,
Where<SOOrderType.orderType, Equal<Required<SOOrderType.orderType>>>>.Select(Base, ordtype);
if (soot != null)
{
var sootext = PXCache<SOOrderType>.GetExtension<SOOrderTypeExt>(soot);
if (sootext != null)
{
PXUIFieldAttribute.SetRequired<SOOrder.customerOrderNbr>(sender, sootext.UsrRequireCustOrdNbr == null ? false : (bool)sootext.UsrRequireCustOrdNbr);
}
}
}
This DOES put an asterisk on the CustomerOrderNumber field - but it doesn't spawn an error upon save if that field is empty.
Another issue is my PXSelect to get the record out of SOOrderType ALWAYS returns a null for the check box user field, even if it has a 'True' value in the database (which is why I put the ternary operator on the call). Even if I hard-code a 'true' value in the PXUIFieldAttribute.SetRequired call, it still doesn't spawn the error to prevent a save. The asterisk is there, but it doesn't work.
If I use a Cache_Attached event to add [PXDefault] it works perfectly - but this doesn't help me - I need it conditionally set.
Any ideas?
Required is used only for displaying the asterisk. PXDefault attribute is the one that makes the field mandatory based on PersistingCheck property value.
The issue is that PXUIFieldAttributes like PersistingCheck can only be set once at the time of graph creation. You can set it dynamically in the constructor/Initialize method but if you change the property after that it has no effects.
When I need a field to be mandatory based on a dynamic condition I remove the PXDefault attribute and validate the field manually in event handlers like RowPersisting:
public void PMTimeActivity_RowPersisting(PXCache sender, PXRowPersistingEventArgs e)
{
PMTimeActivity timeActivity = e.Row as PMTimeActivity;
if (timeActivity != null && PMTimeActivity.timeSpent == null)
{
PXUIFieldAttribute.SetError<PMTimeActivity.timeSpent>(sender, timeActivity, "'Time Spent' cannot be empty."));
}
}
I have a custom field on the CRActivity table in which I need to store the number of records in a related table. I am trying to set the field to the value when screen CR306030 opens. The user needs to be able to override the calculated number so, I'm thinking that I need logic on the calculation to check if the custom field is > 0, in which case, don't populate the custom field and assume it's already been set.
Previously, I've tried to do this in the Field_Selecting events but, this is not working. I'm thinking I might be able to use a PXFormula attribute. Any suggestions?
I tried making a custom attribute which is close but, it won't save the values to the db. The save button enables, I can click it and it looks like it saves but, no dice. Some mundane detail, I'm sure.....
Here's my custom attribute:
public class CFCountIfZeroAttribute : PXIntAttribute
{
public override void FieldSelecting(PXCache cache, PXFieldSelectingEventArgs e)
{
if (e.Row == null)
return;
CRActivity activity = (CRActivity)e.Row;
CRActivityExt activityExt = activity.GetExtension<CRActivityExt>();
if (activityExt.usrCustomField <= 0)
{
int aggregateValue = BQLToFind();
e.ReturnValue = aggregateValue;
cache.SetValue<CRActivityExt.usrCustomField>(e.Row, aggregateValue);
cache.IsDirty = true;
}
}
}
Thanks!
I don't think I've ever done a count within a PXFormula, but what if you created a custom attribute?
[DBUIInt()]
[EditableCount()]
public virtual int? CountField
public class EditableCountAttribute
{
public override void FieldSelecting(PXCache sender, PXFieldSelectingEventArgs e)
{
if (e.Row != null)
{
//if CountField is 0, lookup the count from another table
}
}
}
This is just off the top of my head. You could pass the field you're counting into the attribute if you wanted to do this elsewhere.
I have extended the CRMarketingListMember DAC in order to include a number of unbound fields. I'm adding these new unbound fields to the List Members grid on CR204000 and need to execute some code in order to put values into these fields when the List Members grid is displayed. The problem is that my unbound fields are always blank in the grid. I've tried extending the CRMarketingListMaint graph and putting the code that populates the unbound fields into the CRMarketingList_RowSelected() event but that, of course, doesn't work.
Thanks for the help!
RowSelecting is the proper event in which to populate unbound fields, if doing additional BQL selects make sure to wrap the logic in a new PXConnectionScope.
Example Below :
public virtual void ARInvoice_RowSelecting(PXCache sender, PXRowSelectingEventArgs e)
{
ARInvoice row = e.Row as ARInvoice;
if (row != null)
{
using (new PXConnectionScope())
{
ARRegisterExtension rowExt = PXCache<ARRegister>.GetExtension<ARRegisterExtension>(row);
var result = PXSelect<.....>
rowExt.UsrISExternalTax = result.IsExternalTax;
}
}
}
I have set my invoice to Manual Numbering
And I want to assign the invoice number(RefNbr) - if blank, before saving the invoice (AR301000). I've overridden the RowPersisting event as follow:
public class ARInvoiceEntry_Extension:PXGraphExtension<ARInvoiceEntry>
{
protected void ARInvoice_RowPersisting(PXCache cache, PXRowPersistingEventArgs e, PXRowPersisting InvokeBaseHandler)
{
var row = (ARInvoice)e.Row;
if (row != null)
{
//BB-<timestamp> as inv# for testing only
if (string.IsNullOrEmpty(row.RefNbr))
row.RefNbr = "BB-" + DateTime.Now.ToString("hhmmsstt");
}
if(InvokeBaseHandler != null)
InvokeBaseHandler(cache, e);
}
}
If I raised a new invoice w/out any lines and saved it. It correctly assigned the Reference Nbr as expected.
Problem is if I raised a new invoice WITH lines. Its complaining that the RefNbr is blank.
What am I missing ? How do I fix this ? Thanks.
Acumatica's PXDBDefaultAttribute only updates field of the dependent records when both the source field of the parent record and the foreign key field of the dependent record are not empty.
When a dependent record is inserted into the cache, PXDBDefaultAttribute will copy the source field value from the parent record to the field it decorates from the dependent record. While the framework is saving new parent record into the database, it first raises RowPersisting event for the parent record. PXDBDefaultAttribute subscribes to the RowPersisting event of the parent record type to save the original source field value:
to locate the parent record after it was saved to the database
or to use it as a restore point for the dependent field in case of an aborted transaction
Also, PXDBDefaultAttribute subscribes to the RowPersisting event of the dependent record type to update the foreign key field with the actual source field value, that has just been recorded in the database. To update the foreign key field PXDBDefaultAttribute must first locate the parent record using the original source field value obtained earlier in the RowPersisting event handler of the parent record type. In case the foreign key field value appears to be empty, there is no chance for PXDBDefaultAttribute to locate the parent record for it and it simply leaves the dependent field empty. This is what eventually is causing the error "RefNbr cannot be empty".
With all that being said, I believe it won't be possible to achieve the desired results if leaving AR Invoice Reference Number empty until it gets saved to the database. As an alternative, let me suggest to default AR Invoice Reference Number to some constant, like < ENTER >, and at the same time replace it with the actual number within the ARInvoice_RowPersisting handler:
using PX.Data;
using System;
namespace PX.Objects.AR
{
public class ARInvoiceNumberingCstAttribute : ARInvoiceType.NumberingAttribute
{
public const string EnterRefNbr = "<ENTER>";
protected override string GetNewNumber()
{
string newNumber = base.GetNewNumber();
if (string.IsNullOrEmpty(newNumber))
{
newNumber = EnterRefNbr;
}
return newNumber;
}
public override void RowPersisting(PXCache sender, PXRowPersistingEventArgs e)
{
if (GetNewNumber() == EnterRefNbr) return;
base.RowPersisting(sender, e);
}
}
public class ARInvoiceEntry_Extension : PXGraphExtension<ARInvoiceEntry>
{
[PXRemoveBaseAttribute(typeof(ARInvoiceType.NumberingAttribute))]
[PXMergeAttributes(Method = MergeMethod.Append)]
[ARInvoiceNumberingCst]
protected void ARInvoice_RefNbr_CacheAttached(PXCache sender)
{ }
protected void ARInvoice_RowPersisting(PXCache cache, PXRowPersistingEventArgs e,
PXRowPersisting InvokeBaseHandler)
{
if (InvokeBaseHandler != null)
InvokeBaseHandler(cache, e);
var row = (ARInvoice)e.Row;
if (row != null)
{
//BB-<timestamp> as inv# for testing only
if (row.RefNbr == ARInvoiceNumberingCstAttribute.EnterRefNbr)
row.RefNbr = "BB-" + DateTime.Now.ToString("hhmmsstt");
}
}
}
}
