How to Calculate in Nav ?

Rana · 2009-10-29

Dear all,

I have created a Table, say Packing Lines. Primary keys are :- "Document Type","Sales Doc. No.","Sales Doc. Line No.",Item,"Line No.".

There is a "Quantity" field in this Table. I want to sum up this field's value at time of entring value. So I have written a Function Say CheckSaleInvoiceLineQty and call this function in the Quantity - OnValidate()

CheckSaleInvoiceLineQty()
TotQty :=0;
PackingLines.SETCURRENTKEY("Document Type","Sales Doc. No.","Sales Doc. Line No.",Item,"Line No.");
PackingLines.SETRANGE("Document Type","Document Type");
PackingLines.SETRANGE("Sales Doc. No.","Sales Doc. No.");
PackingLines.SETRANGE("Sales Doc. Line No.","Sales Doc. Line No.");
IF PackingLines.FINDSET THEN
    REPEAT
      TotQty+= PackingLines.Quantity ;
    UNTIL PackingLines.NEXT = 0;

When I am entering any value in the quantity field the function is executed and enter into the REPEAT

UNTIL Loop , but finds PackingLines.Quantity =0 value. why ?
:shock: :shock: :shock:

Try: packinglines.modify;

from which object and in which trigger this function is run?
CheckSaleInvoiceLineQty()

you're reading a record variable, it means that if ther record is not committed to the database, you won't see it in an instance of your table.

If you are calling it from OnValidate of new line, you will not see this line in the loop, because it was not inserted yet. You need to add the actual value from Rec and subtract the old value from xRec to have correct value.

This is not working correctly! :shock: :shock: :shock:

Try this code ....

TotQty :=0;
PackingLines.SETCURRENTKEY("Document Type","Sales Doc. No.","Sales Doc. Line No.",Item,"Line No.");
PackingLines.SETRANGE("Document Type","Document Type",);
PackingLines.SETRANGE("Sales Doc. No.","Sales Doc. No.");
PackingLines.SETRANGE("Sales Doc. Line No.","Sales Doc. Line No.");
PackingLines.SETFILTER("Line No.",'<>%1',"Line No");
IF PackingLines.FINDSET THEN BEGIN
  REPEAT
   TotQty+= PackingLines.Quantity;
  UNTIL PackingLines.NEXT =0;
   TotQty += Qty;
END;

Use a flow field.

END;

What is Qty? I assume that you need to add Rec.Quantity and not Qty...

Qty is a parameter.Which is nothing but Rec.Quantity .

If you are modifying the record, you need to subtract xRec.Quantity and add Rec.Quantity, if you are inserting record, you need only add the Rec.Quantity.

Could you describe some example of data an the result?

I'm creating the Packing List lines against a Sales Invoice Line. And try to block that The Packing Lines total quantity could not exceed the Sales Line Quantity

I know, I though that you write which data you have in the table, which result you got, what you want to have as result ... example with data and what is wrong ("I have these records.... and when I enter XXX into new line, the sum is AAA but it should be BBB")
