It is not clear from your posts why you would have two batches displayed, an unposted and an open batch.

There is a setting in your company profile that controls what you are allowed to edit in retrieved batches. Your organization may have strict rules about what edits are allowed. Check before changing this setting.

It's a pity you weren't able to attend the Adagio Open House in Montreal last week, We could have shown you have all these functions work.

Perhaps it would be good to invest a few dollars in your Adagio consultant rather than trying to disentangle this yourself.
