Hi,
Please close your duplicated thread. Remember, the key word in B1 table is generally 3 letters. RIN means AR Credit Memo. INV means AR Invoice. If there is link within them, they are linked by INV1.TrgetEntry=RIN1.DocEntry and INV1.LineNum=RIN1.BaseLine. Otherwise, you need stick on the same marketing document such as ORIN with RINXX.
Thanks,
Gordon
