Do you have Batch Control by User turned on in Bank Book setup?
Verify that all Bank Book , Transaction Types are setup as follow:
If the Transfer Type box is checked, the Distribution Account MUST be a Cash Account
If the Transfer Type is NOT checked, the Distribution Account Must NOT be a Cash Account
(and, of course, if the Distribution Account is a Cash Account, the Transfer Type box MUST be checked)
Also, verify the Transaction Type in Bank Book setup for Check Reversal Trx Type is NOT
a Transfer Type Transaction Type (the Transfer Type box is NOT checked on this Transaction Type maintenance screen)
When all Bank Book Transactions are posted:
Go to System Manager, Processes, Initialize Accounting, Bank Book Files
check ONLY B/B Batch ID File (BBIDFIL) and B/B Transaction File (BBTRXFIL)
DO NOT Initialize ALL
There might be something 'stuck' in one of the above tables mentioned
