Settlement, CJ8G no error, CJ88 with error

Hi Experts,

While I settle project via CJ8G, there are no error messages. But the WBS is not settled. Whereas when I try to settle same project via CJ88, the WBS displays error "Allocation structure is not correct".

how to ensure that the error messages in CJ88 is also displayed in CJ8G? Since users use only CJ8G and NOT CJ88 in month end closing process.

Thanks.
