Known limitations

The inventory behaviour of all three options has been verified by testing. Each option's outcome is described below.

• Return to Stock: this is completely standard, unmodified Business Central behaviour. There's nothing new to verify.
• Credit Only - No Stock Change: verified by testing. The customer and G/L side posts the full credit, and on-hand inventory is unchanged before and after. This option works exactly as intended.
• Credit + Write Off Stock: on-hand inventory is unchanged, exactly like Credit Only; this is correct, not a bug. Testing confirmed on-hand nets to zero, the same as Credit Only. Why: the goods behind this option already left inventory in their original sale, which already reduced stock at that time. The customer never ships anything back. The only correction this credit memo needs to make is cancelling the automatic physical return Business Central would otherwise assume, not removing stock a second time, which would double-count a loss that only happened once. The only real difference between Credit Only and Credit + Write Off Stock is an internal tag on the transaction that lets inventory reports later distinguish "credited as a genuine return" from "credited but written off as damaged" (see Reporting); it doesn't change the stock count either way.
• Automated regression testing: real posting scenarios are covered by automated regression tests that assert the outcomes above; this is part of ongoing development, not something end users need to act on.

Posted document presentation: the synthetic wash line is not shown on the Posted Sales Credit Memo; the posted document lists only the lines you entered. The offset it provides lives in the item ledger (two Item Ledger Entries that net to zero on-hand), never as a visible document line. This matches the behaviour of the previous TRIMIT solution, whose posted credit memos also never showed the internal reversal line.
