Populate Unit Cost for Serialized Item in custom field SOLine - acumatica

Question

I need to populate a custom column (User Defined Cost) in SOLine from a Serialized Item Unit Cost from Purchase Receipts with the same Lot/Serial Number (screenshot 1). If the item has splited Lot/Serial number (screenshot 2) then respective unit cost I have to read based on Lot/Serial number user enters in SOLine item.
I have already written SOLine_RowPersisting event to handle if the item is not splited but not sure how to find if there is a splited Serialized items. Below is the code for SOLine_RowPersisting event. Please suggest.
protected virtual void SOLine_RowPersisting(PXCache sender, PXRowPersistingEventArgs e)
{
SOLine row = (SOLine)e.Row;
if (row == null)
return;
if (!string.IsNullOrEmpty(row.LotSerialNbr))
{
SOOrderEntry graph = PXGraph.CreateInstance<SOOrderEntry>();
//select UnitCost, * from POReceiptLine where CompanyID = 2 and ReceiptNbr = 'PR004082' and InventoryID = '8502' and LotSerialNbr = 'SUB1703210365'
//select LotSerialNbr, * from POReceiptLineSplit where CompanyID = 2 and InventoryID = '8502' and LotSerialNbr = 'SUB1704270366'
//TODO : How to get it from POReceiptLineSplit also
POReceiptLine poRow = PXSelect<POReceiptLine,
Where<POReceiptLine.inventoryID, Equal<Required<POReceiptLine.inventoryID>>,
And<POReceiptLine.lotSerialNbr, Equal<Required<POReceiptLine.lotSerialNbr>>,
And<POReceiptLine.pOType, Equal<Required<POReceiptLine.pOType>>>>>>.Select(graph, row.InventoryID, row.LotSerialNbr, "RO");
SOLineExtension ext = PXCache<SOLine>.GetExtension<SOLineExtension>(row);
ext.UsrUserDefinedCost = poRow.UnitCost;
}
}

Answer 1

You can iterate on the POReceiptLineSplit records from the 'splits' DataView of the Base DAC.
To do that, open the grid in Acumatica, hold Control+Alt and click on it. This will bring a popup with the DAC name of the records contained in the grid.
From there select your customization project. Click on 'Grid: splits', the DataMember property of the grid is 'splits'. This is the name of the DataView from the Base class.
With that information, you can iterate content of the grid from the graph extension. Note that we use the Base prefix because we reference the base graph from within the extension.
       foreach (POReceiptLineSplit split in Base.splits.Select())
       {
          PXTrace.WriteInformation("ReceiptNbr: {0}{1}LineNbr: {2}{3}SplitLineNbr: {4}",
                                   split.ReceiptNbr, Environment.NewLine,
                                   split.LineNbr, Environment.NewLine,
                                   split.SplitLineNbr);
       }

It is SOLineSplit_LotSerialNbr_FieldUpdated event need to extend in SOOrder Extension and POReceiptLine_RowSelected in POReceiptEntry Extension. Below code will help get unit cost from purchase receipt.
POReceiptLine poRow = PXSelectJoin<POReceiptLine,
LeftJoin<POReceiptLineSplit,
On<POReceiptLine.receiptNbr, Equal<POReceiptLineSplit.receiptNbr>,
And<POReceiptLine.inventoryID, Equal<POReceiptLineSplit.inventoryID>,
And<POReceiptLine.lineNbr, Equal<POReceiptLineSplit.lineNbr>>>>>,
Where<POReceiptLine.inventoryID, Equal<Required<POReceiptLine.inventoryID>>,
And<POReceiptLineSplit.lotSerialNbr, Equal<Required<POReceiptLineSplit.lotSerialNbr>>,
And<POReceiptLine.receiptType, Equal<Required<POReceiptLine.receiptType>>>>>>.Select(graph, row.InventoryID, row.LotSerialNbr, "RT");
