Thanks for the update. I mis-read the original post and thought the batch was entered in BankRec, then retrieved to AP.

The same logic still applies, where Payables manual check or system check payments will not allow entry/posting of a check related to a bank different than the one assigned to the vendor's control account set, if the option has been enabled in the company profile. Can I assume then that you were allowed to enter/post the check(s) in Adagio Payables, but are getting an error message when attempting to post the retrieved batch in BankRec?

With current versions of Payables 8.1E and BankRec 8.1D, I cannot replicate this scenario - entry and posting is halted in AP, before the batch is posted and retrieved into BankRec.

To see what is happening, in BankRec highlight the batch you retrieved from AP and click the Rename button. Note the Bank Code assigned to the batch - is it the one you expected? If not, then you should investigate how your BankRec Bank codes are defined, specifically which AP bank codes they are mapped to. It is possible that you have multiple BankRec bank codes assigned to the same AP bank, and the batch was retreived to a bank you didn't expect. Or a BankRec bank code is mapped to the wrong bank that you aren't expecting. Edit the BankRec bank record and the Interface tab.

If the correct BankRec bank code is assigned to the retrieved Payables check batch, and each BankRec bank code is assigned to a unique AP bank code, then the likely problem is the AP control account sets and the banks assigned. Perhaps somebody enabled the 'Include bank with control account set' option when it should not have been.

You'll probably need to get your Adagio consultant involved with this question, so they can look at your company setup (banks, batches, etc) with you.
