This is my current requirement.
I need to validate Is tax code exists in the Sales order document lines. I have created a Sales order as Draft document . Then I added the same from the Draft document to the ORDR document. Now My sales order is in Open status. Now I want to update the document lines with the tax code. But am not able to edit the dcoument lines at all. I checked for the document status as well as the line status. Both the status are open only. How to enable the document lines.
Thanks in Advance !
