Return code/CYT module does not concur with BCA setting

What causes this issue?

The capital yield tax (CYT) module has supplied the return code &v1&
(for dialog processing), although CYT batch processing was set in the
bank current accounts system.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

The CYT module must transfer the return code '1' to BCA for batch
processing. If you opt for dialog processing you must enter this in the
basic settings for conditions.
