Understanding these considerations is essential before making cost changes to avoid unexpected cost adjustments during sales transactions. ## Key points - Updating standard cost on the item card does not automatically update standard costs on related stock keeping units for specific locations - Existing on-hand inventory retains its original cost and is not revalued when you change the standard cost - When you sell items after a cost change, the system initially uses the new cost but cost adjustment reverts it to the original cost based on value entries - The Standard Cost Worksheet is the proper tool to use if you need to revalue existing inventory - Automatic cost adjustment must be set to 'Always' or you must manually run 'Adjust Cost - Item Entries' to see cost adjustments ## Quotes - "The system doesn't update the standard cost of any Stock Keeping Units." (This is a critical gotcha when changing costs on the item card with location-specific SKUs, requiring manual updates to avoid posting at incorrect costs) - "Existing on-hand inventory is not revalued when you change the Standard Cost on the Item Card." (This explains why sold items revert to original costs through adjustment, a common source of confusion in standard costing implementations) - "If you need your on-hand stock revalued to the new cost, the Standard Cost Worksheet is the tool for the job." (Provides the correct procedural guidance for users who need to actually revalue existing inventory rather than just change the cost) ## AL objects mentioned As named in the post.
