We need to delete an item in the SAP Customer Checkout that was already used in a reserve invoice and the item doesn't exist anymore in the SAP B1.
The KBA 2670178 says that it is possible to delete article and customer in SAP Customer Checkout if they are not used in a receipt.
It also says that we can set the item to inactive, but this option inactivates all items.
Is there an option to disable a specific item?
As mentioned in the KBA 2670178 it is not possible to delete articles that were already used in any transaction.
The recommendation in this scenario is to use the option "Set articles to 'Inactive'". It will set all items to inactive, then, later it is necessary to run the complete article synchronization again.
A full synchronization with the ERP system ensures that all relevant articles remain active.
In this case, the item that doesn't exist in the SAP B1 will remain inactive in the CCO.
