Executing Query takes time - acumatica

I have an extended table on Inventoryitem having 100 fields. I have written a smart search to show data based on the filter condition.
Item master having 25.000+ records
For fetching all the records it takes around 3 mins.
public PXSelectOrderBy<
FilterResult,
OrderBy<
Asc<FilterResult.inventoryID,
Asc<FilterResult.recordType>>>> records;
[System.SerializableAttribute()]
[PXTable(typeof(InventoryItem.inventoryID),
IsOptional = true)]
public class ItemExtendTable : PXCacheExtension<InventoryItem>
{
}
[PXFilterable]
public PXSelectJoinGroupBy<
INSiteStatus,
LeftJoin<InventoryItem,
On<InventoryItem.inventoryID, Equal<INSiteStatus.inventoryID>>>,
Aggregate<
GroupBy<InventoryItem.inventoryID,
Sum<INSiteStatus.qtyOnHand>>>>
item;
I am using the following statement to fetch a page data in the data delegate
protected virtual IEnumerable Records()
{
List<object> result = new List<object>();
List<FilterResult> rows = new List<FilterResult>();
PXView select = new PXView(this, true, item.View.BqlSelect);
Int32 totalrow = 0;
Int32 startrow = PXView.StartRow;
result = select.Select(PXView.Currents, PXView.Parameters,
PXView.Searches, PXView.SortColumns, PXView.Descendings,
PXView.Filters, ref startrow, PXView.MaximumRows, ref totalrow);
PXView.StartRow = 0;
foreach (PXResult<INSiteStatus, InventoryItem> res in result)
{
InventoryItem item_rec = res;
ItemExtendTable item_ext = PXCache<InventoryItem>.GetExtension<ItemExtendTable>(item_rec);
FilterResult ret = new FilterResult();
// Fill values
rows.Add(ret);
}
return rows;
}
**
result = select.Select(PXView.Currents, PXView.Parameters,
PXView.Searches, PXView.SortColumns, PXView.Descendings,
PXView.Filters, ref startrow, PXView.MaximumRows, ref totalrow);
**
The above statement takes more than 3 mins to fetch data.
Using Extended table having impact on BQL query?
Update
I have run profile and it fires SQL Statement for each item. It fired more than 25000+ SQL Statement.

Unable to open SO screen SO301000 using Action from Quote screen CR304500

I have created a Action called CREATE SO in Sales Quote screen to create Sales order.
I am unable to open the sales order screen using this action. though the sales order is getting created
but the SO screen is not opening while creating the SO. I am not sure where i am making mistake in my code. Please suggest. Thanks.

The issue is that the redirection is in the PXLongOperation. A PXLongOperation starts a separate thread that is not related with the UI. In order to solve this you can use the PXCustomInfo structure to talk back with the UI thread after the long operation finishes and thus be able to redirect to the so screen.
// PXCustomInfoDefinition
public sealed class SORedirectionCustomInfo: IPXCustomInfo
{
private PXGraph _OrderGraph;
public SORedirectionCustomInfo(PXGraph orderGraph)
{
_OrderGraph = orderGraph;
}
public void Complete(PXLongRunStatus status, PXGraph graph)
{
if (status == PXLongRunStatus.Completed && graph is <YourQuoteGraphType>)
{
throw new PXRedirectRequiredException(orderGraphObjet, "Document") { Mode = PXBaseRedirectException.WindowMode.NewWindow };
}
}
}
// Long Operation Method
public virtual void CreateSalesOrderMethod(CRQuote quote, List<CROpportunityProducts> QuoteList)
{
// Your code to create SO....
if (var_orderCreated)
{
PXLongOperation.SetCustomInfo(new SORedirectionCustomInfo(orderGraphObjet));
}
}
This should be able to redirect successfully once the long operation is completed and the order is created.

Unable to give string as first parameter in dictionary Acumatica 2019R2 (Device hub print related)

I am unable to give a string as the first parameter in dictionary Acumatica 2019R2

// Add Report Parameters
PrintSettings printerSettings = new PrintSettings()
{

DefinePrinterManually = true,
PrinterID = , //Set the printer id of the printer you want to use

Shipment Confirmation and Update IN through code is not working

I have a requirement to create shipment document, shipment confirmation and update In on a Sales order Transfer document.
The following code is used for shipment confirmation
public string CreateShipment()
{
bool flag = false;
string _retval = string.Empty;
using (IEnumerator<PXResult<SOOrderShipment>> enumerator = Base.shipmentlist.Select(Array.Empty<object>()).GetEnumerator())

throw new PXException(Mess);
}

//sOOrderEntry.Caches.Clear();
SOOrder sOOrder = Base.Document.Current;
int? nullable = new int?(0);
int? customerLocationID = new int?(0);
if (sOOrder != null)
{
nullable = sOOrder.CustomerID;
customerLocationID = sOOrder.CustomerLocationID;
}
int? siteID = new int?(0);
//SOShipmentEntry sOShipmentEntry1 = PXGraph.CreateInstance<SOShipmentEntry>();
SOShipment destinationDocument = sOShipmentEntry.Document.Insert();
destinationDocument.ShipmentType = "T";
destinationDocument = sOShipmentEntry.Document.Update(destinationDocument);
destinationDocument.Operation = "I";
destinationDocument = sOShipmentEntry.Document.Update(destinationDocument);
using (IEnumerator<PXResult<SOLine>> enumerator1 = PXSelectReadonly<SOLine, Where<SOLine.orderType, Equal<Required<SOLine.orderType>>, And<SOLine.orderNbr, Equal<Required<SOLine.orderNbr>>>>>.Select(Base, new object[] { Base.Document.Current.OrderType, Base.Document.Current.OrderNbr }).GetEnumerator())
{
if (enumerator1.MoveNext())
{
SOLine line = (SOLine)enumerator1.Current;
siteID = line.SiteID;
}
}
destinationDocument.SiteID = siteID;
destinationDocument.DestinationSiteID = sOOrder.DestinationSiteID;
destinationDocument = sOShipmentEntry.Document.Update(destinationDocument);
//sOOrderEntry.Document.Current = sOOrder;
if (Base.Document.Current != null)
{
DocumentList<SOShipment> documentList = new DocumentList<SOShipment>(sOShipmentEntry);
sOShipmentEntry.CreateShipment(Base.Document.Current, sOShipmentEntry.Document.Current.SiteID, sOShipmentEntry.Document.Current.ShipDate, new bool?(false), "I", documentList);
if (sOShipmentEntry.Document.Current.ShipmentNbr != null)
{
SOOrderEntry sOOrderEntry1 = PXGraph.CreateInstance<SOOrderEntry>();
sOOrderEntry1.Clear();
sOOrderEntry1.Document.Current = sOOrder;
int? openShipmentCntr = Base.Document.Current.OpenShipmentCntr;
if ((openShipmentCntr.GetValueOrDefault() > 0 ? openShipmentCntr.HasValue : false))
{
sOOrder.Status = SOOrderStatus.Shipping;
sOOrder.Hold = new bool?(false);
sOOrderEntry1.Document.Update(sOOrder);
sOOrderEntry1.Save.Press();
_retval = sOShipmentEntry.Document.Current.ShipmentNbr;
}
}
}
return _retval;
}
The following code confirms the shipment and update IN.
private void ConfirmShipment(string shipmentnbr)
{
SOShipmentEntry sOShipmentEntry = PXGraph.CreateInstance<SOShipmentEntry>();
SOOrderEntry sOOrderEntry = PXGraph.CreateInstance<SOOrderEntry>();

if(sOShipmentEntry.Document.Current!= null && sOOrderEntry.Document.Current != null)
{
sOShipmentEntry.ConfirmShipment(sOOrderEntry, sOShipmentEntry.Document.Current);
sOShipmentEntry.UpdateIN.Press();
}
}
I am able to select sales order in purchase receipt transfer document, but the shipment document status still shows open and not completed.
I have tried the run confirm shipment on the document which is already confirmed through code from the menu of shipment document and I am getting the following error
“Shipment counters are corrupted.”

Best Practice to limit NotesViewEntryCollection from getAllEntries

I want to create better web service that display collection from NotesView with pagination.
And I have found some performance issue of View.getAllEntries from bigger view.
On MongoDB, I can use findAll() with skip() and limit().
How can I do like that on Domino ?
Use the ViewNavigator class. If you are paging through a large view, it is much faster than view.getAllEntries().
You can acquire an instance of ViewNavigator with view.createViewNav() or a similar method. For best performance, call view.setAutoUpdate(false) before you acquire the navigator.
You can find lots more information by searching the web. This article looks like a good place to start.

import lotus.domino.ViewEntry;
private String consultView(View view, int counter,int position) throws Exception{
String strValue = "";
ViewNavigator nav;

view.setAutoUpdate(false);
nav = view.createViewNav();
nav.setEntryOptions(ViewNavigator.VN_ENTRYOPT_NOCOUNTDATA);
nav.setBufferMaxEntries(400);
int limit = counter;
int skippedEntries = nav.skip(position);
String number = "";
if (skippedEntries == position) {
Map<Integer, String> columnNameMap = new HashMap<Integer, String>();
for (ViewColumn col : (List<ViewColumn>) view.getColumns()) {
if (col.getColumnValuesIndex() < 65535) {
columnNameMap.put(col.getColumnValuesIndex(), col.getItemName());
}
}
List nodeData = new ArrayList();
ViewEntry entry = nav.getCurrent();
while (entry != null && count <= (limit - 1)) {
if (!entry.isCategory()) {
try {
HashMap<String, Object> entryMap = new HashMap<String, Object>();
count++;
List<Object> columnValues = entry.getColumnValues();
entryMap.put("unid", entry.getUniversalID());

entryMap.put("userpos", count);
for (Integer index : columnNameMap.keySet())
entryMap.put(columnNameMap.get(index).toString(),columnValues.get(index));
nodeData.add(entryMap);
} catch (Exception e) {
e.printStackTrace();
}
}
ViewEntry tmpentry = nav.getNext(entry);
entry.recycle();
entry = tmpentry;
}
JsonJavaObject returnJSON = new JsonJavaObject();
returnJSON.put("errorcode", 0);
returnJSON.put("errormessage", "");
returnJSON.put("total",getViewCount(view));
returnJSON.put("data", nodeData);
strValue = returnJSON.toString();
}
nav.recycle();
view.recycle();
return strValue;
}
private int getViewCount(View view) throws NotesException {

SPQuery search doesn't work with "BeginsWith"

So, my problem is that my knowledge of CAML and Sharepoint is very poor.
Question: I need SPQuery for building query search, search text I have from textbox. I expect that my query returns me item(s) (for example, I type in textbox "Jo" and query returns me all items with surname "Johnson", or name "John", etc)
1)TextChanged works ok. I've check it, there is ok
2) SPGridView views items ok. Items from SPList I add to gridView - there are viewd by gridview.
3) But my query doesn't work. Please, help with links/advises

You have to include the field Surname into the view fields of the query:
SPQuery query = // ...
query.ViewFields = "<FieldRef Name='Surname' />";
// ...
You can understand the view fields like the SELECT part of a SQL query.
Have you debugged your code to check the query string that is generated? Also, you have query = query = under the Name switch.
Also, you know that the switch is case sensitive, so ensure you enter your searchQuery option appropriately.
