Bapi for SO change
Hello every body,
For Sales Order Update , I am using BAPI
" BAPI_SALESORDER_CHANGE ".
I could delete So line item and insert line item, successfully.
But for Updating SO line item,
Im also Updating Schedule lines,
My problem is : while updating my line item with new quantity , it is adding the new quantity with existing quantity.
Reason behind this is , this BAPI is creating a new schedule line rather than updating a existing schedule line.
Udate Flag for schedule line is "U", i am passing schd_line number also for update.
If existing SO item Qty is 20.
i want to update it to 30, by passing quantity 30 to BAPI.
After executing BAPI.
Present Qty is 50. But i am expecting 30.
Thanks In advance.
