Support:

There would definitely be some challenges due to the way the current process works, including the fact that the sub-ledger doesn't even store the GL transaction with any user flag.

I suggest that you see what you are allowed to post.

AP Clerk only see those batches they posted. Not posted in AP by other users and not posted in other modules by other users.

Another option would be to post sub-ledger batches directly to GL rather than requiring some option to only retrieve those that you posted.
