Currently there is not automatic way to reverse a posted sales credit memo. Instead you have to create an invoice and use the copy functionality.

Unfortunately if you have FIFO accounting switched on the resulting GL entry is very likely to differ to the original GL entry created by the original Sales Cr. Memo. this is because the FIFO cost point has moved.

Resulting in a different GL posting on the suggested method for a reversal.

Suggestion: provide Sales Cr.Memo reversal functionality which replicates the original GL entry but with the opposite sign.

Thanks for listening
