remove reference batch

Depends on how you did it?

ZBBL is NOT an SAP transaction. We would have no idea what this transaction does for you or doesn't. If it use standard SAP material movements behind it, its possible you can reverse these using MBST or MIGO. But you would have to understand them and know what they do. Then you would also need to know what other things your ZBBL transaction does. It could be making other updates to records like the batch record or process orders.

We'd have no way of knowing or guiding you on this.
