My client got an error message "Unit price must be 0 in Sales Line Document Type = ‘Credit Memo’, Document No. = ‘00279’, Line No. =‘20000’. " when she posted Credit Memo.
Actually, I have never used Credit Memo for G/L Account. Although I believe it is possible to use, I do not know how to resolve this error.
Could anyone give me any advice?
I seriously need help, any reply is really appreciated.
Thanks in advance.
