Start with the product and slot whose balance differs from reality. A total balance can hide stock recorded in the wrong slot or purchase batch.
- Check product balances by warehouse and slot.
- Open warehouse events and filter by product and period.
- Compare receipts, sales, transfers, reservations, returns and stocktakes.
- Check Number of products left unremoved on exceptional events.
- Investigate the related work or original entry before correcting.
An Additional event may indicate that a deduction was also processed from another slot. Examine related events together; one row may not describe the whole deduction.
Once the event sequence is understood, correct the actual error. If physical stock differs and no missing receipt or transfer explains it, perform a stocktake and describe the reason. This helps the next investigator understand the change.
