I recently did an upgrade to Adagio Payables 8.1C and I seem to have lost the capability to move a printed cheque from the batch it is currently in to a new batch.

Do you use MultiCurrency? If so then copying checks is correctly prevented, should the banks be of different currencies.
Do you have 'Include bank in control account set' defined in the cmpany profile? If so then copying checks is correctly prevented.
Printed checks can no longer be Moved to a different batch (ie the original check is deleted), nor are printed checks able to be copied if you do not increment the document number. This is to maintain integrity of the data and was done on purpose.

Are you trying to correct a mistake when a check was printed in the wrong batch? Or do you regularly print checks in one batch and then copy them to a different batch?

I don't use multicurrency and i don't have include bank in control set.

Our controller likes us to have cheques ran in different months put in different batches and i made an error by putting 2 November cheques into my October batch.

I managed to copy them to a new batch by updating the document number and deleted them from the old batch.
Thank You for your help

You got the solution before I posted it. Good to go.
