Bill:

We need to clarify which "consolidation" process you are referring to (there are 3). I interpret from your question that the consolidation happens in the subledger before retrieval to the Ledger. If that is the case, there are 5 options on how to consolidate. Two of them use the actual transaction date and one allows you to specify the date. If the consolidation occurs in the subledger, that batch, once posted in the Ledger, can be unposted like any other batch.

If the consolidation happens in the Ledger itself, using one of the other consolidation options, you cannot unpost the batch. I suspect that is what has happened in your case, based on Support's testing.
