I am facing the issue "There can be only one transaction per voucher "when validating AP
This is standard validation. When the invoice journal(or journal general with invoice number) is used, the system will allow only one voucher per one vendor transaction line(multiple vendor lines cannot have same voucher)
Thanks for reply, I had found the solution.
If possible, please let us know the solution. It might help others.
Voucher number was same with all vendor because my client have enter the offset account in the end that’s why system was generated the same invoice number. If you filled all the field with offset account as well against vendor transaction system will generate a new voucher number in new row. I just have update the Voucher number sequence through job.
