We see lots of hanging queues from EWM to ERP system due to the various reasons. Some of these may be resolved with the master data corrections or number ranges just to name a few. There are few related to the transactional data such as posting period closure or duplicate HUs etc.

It is a very tedious activity for the technical/functional team member to clear these failed queues to keep both the systems in sync..

If these failed queues can't be resolved using the standard procedures, then last option is debug the code in the production environment and change the value during the runtime. This is not a good practice but no other options.

To overcome this issue, SAP has provided a simple solution to edit the failed queues. The queue contents can be edited or deleted based on the settings provided. The changes can be done at the field level where in the deletion happens at the table level.

The user with having the relevant roles can edit the queues and make the changes. Once the changes are saved, the system processes the same again.
