How posting works
You don't need to do anything differently when posting a credit memo that uses Credit Only or Credit + Write Off Stock; posting works the same way it always has (Ship and Invoice, Invoice, whichever your process uses). Behind the scenes, for every line not set to Return to Stock:
- Immediately before posting, the extension inserts an extra, internal-only line for the same item, location, and variant as your line, with the quantity flipped to negative and the unit price set to zero.
- Standard Business Central posting then creates an Item Ledger Entry for both your original line and this internal line, exactly as it would for any two ordinary lines.
- For Credit + Write Off Stock specifically, the internal line's resulting entry is re-tagged from "Sale" to "Negative Adjustment" before it posts, for inventory reporting purposes (see Reporting).
- The customer ledger and G/L entries for your original line are completely unaffected by any of this; only the item/inventory side is touched.
- The internal line is never shown on the document, before or after posting. It exists only for the moment posting happens, to create the offsetting Item Ledger Entry; the Posted Sales Credit Memo lists only the lines you entered. This matches how the same feature behaved under the previous TRIMIT solution.
