I'm getting this error when i post only the filled purchase lines in the invoice. The lines from 100000-150000 are filled correctly.But when I post its showing:- No. must have a value in Purchase Line: Document Type=Invoice, Document No.=EXP/CMUM/20-21/00161, Line No.=160000.It cannot be zero or empty. Although, line No. 160000 is unfilled or empty its throwing this error. Anyone kindly provide solution for this problem.
