Transmission error on after running Process Lockboxes

Hello Colleagues,

The business user requirement is to update the GL account of a bank from 1931000 to 1931099 . First, I update the cash in the general account from CM Responsibilities. Next, I end-dated the Receipt method, Batch Sources and lockboxes then create a new one with the correct GL account. After that, when business users try to do the testing. She/he encountered an issue regarding transmission. Is there something wrong with my setup? Could someone provide an answer or a step/process of what is needed to consider when changing the GL cash accounts on the

bank? I attached here the result of the user's testing. Thank you.
