3806982 - Error "Action BOM_HANDLING not possible; reference object does not exist" when discarding product draft in Manage Product Master Data - SAP S/4HANA Cloud Public Edition

• When editing a product in the Manage Product Master Data app and canceling/discarding the changes without updating the draft, an error occurs and the draft cannot be discarded.
• The behavior can occur for products with and without a BOM and for standard or custom fields (for example, setting “Compliance Relevant” to “No” and then discarding without pressing Enter).
• OData v2 request fails with HTTP 400 during DELETE of the draft entity.
• Error message: /BOBF/FRW_COMMON 004 — “Action BOM_HANDLING not possible; reference object does not exist”.
• Gateway error may be logged: /IWFND/CM_MGW 004 — “Rejected because of error during changeset processing”.

1. Open the Manage Product Master Data app.
2. Open a product and choose Edit.
3. Change a field value (for example, set “Compliance Relevant” to “No”) and do not press Enter (do not update the draft).
4. Cancel and choose to discard the edit.
5. Observe that an error is raised and the draft is not discarded.

A backend logic issue causes the BOM_HANDLING action to be called after the draft deletion during discard, leading to “reference object does not exist” and blocking the discard.
