Hard code limit to 100% PO receipt

Hi ​@Harry  You can write a logic to validate in the AP Bill screen graph extension like below.

Graph Extension — RowInserting / RowPersisting Override  
Extend the APInvoiceEntry graph and add a validation that checks receipt completion before allowing the bill to be saved.

Hope this helps!
 

public class APInvoiceEntry_Extension : PXGraphExtension<APInvoiceEntry>
{
    public override void Initialize()
    {
        base.Initialize();
    }

    protected void _(Events.RowPersisting<APInvoice> e)
    {
        if (e.Operation == PXDBOperation.Insert || 
            e.Operation == PXDBOperation.Update)
        {
            APInvoice bill = e.Row as APInvoice;
            if (bill == null) return;

            if (!IsReceiptFullyReceived(bill))
            {
                e.Cache.RaiseExceptionHandling<APInvoice.refNbr>(
                    bill,
                    bill.RefNbr,
                    new PXSetPropertyException(
                        "AP Bill cannot be created. The linked PO Receipt is not 100% complete.",
                        PXErrorLevel.Error));

                e.Cancel = true;
            }
        }
    }

    private bool IsReceiptFullyReceived(APInvoice bill)
    {
        // Query POReceiptLine to check if all lines are fully billed
        var receiptLines = PXSelectJoin<POReceiptLine,
            InnerJoin<APTran,
                On<APTran.receiptNbr, Equal<POReceiptLine.receiptNbr>,
                And<APTran.receiptLineNbr, Equal<POReceiptLine.lineNbr>>>>,
            Where<APTran.tranType, Equal<Required<APTran.tranType>>,
                And<APTran.refNbr, Equal<Required<APTran.refNbr>>>>>
            .Select(Base, bill.DocType, bill.RefNbr);

        foreach (PXResult<POReceiptLine, APTran> row in receiptLines)
        {
            POReceiptLine receiptLine = row;

            // Compare received qty vs billed qty
            if (receiptLine.ReceiptQty > receiptLine.BilledQty)
            {
                return false;
            }
        }

        return true;
    }
}
