I would like post a Credit Memo (Invoice Type: Correction)
I filled the Corrective Invoice tab (Correction type: unit price), then Functions -> Get Correction Lines. Modify the Unit price, then Functions -> Create Sales Line, and Post the Credit Memo.
I get an error message: "Amount must be negative in Gen. Journal Line Journal Template Name = '' Journal Batch Name = '' Line No. = 0."
I get this error only if i want to increase the Unit Price, when I want to decrease the Unit Price, I can post the memo.
Could you help me, please?
