How to Create Credit Memo Via FBDI and Applied to an Invoice Without Copying the Latter Memo Line

Summary:

Credit Memos created via FBDI and applied to an invoice via FBDI results to a memo line the same with the invoice. For example:

Line 1: Invoice with memo line of "STORAGE"

Line 2: Credit memo with memo line of "CWT"

Upon uploading this FBDI into the system, the invoice (line 1) created in the system has "STORAGE" memo line while the credit memo has "STORAGE" memo line as well.

Is there a configuration to prevent overriding the memo line of the credit memo in the FBDI?
