Errors as below occur you when Export during step 3 of new bank statment.
An error occurred during file export:
Error ID: AP_UI_OIN 022
Error text: Export failed due to errors in the template configuration:
Cardinality of Association 'ITEM' is not a to-1 association
Unknown element 'ITEM' of 'FOPXP_BANKSTAT~ITEM' for type 'ESF'
SAP Business Bydesign
Reproducing the Issue
Go to Liquidity Management work center and Bank Statement View.
Select bank statement XXX (XXX stands for bank statement ID) which is in preparation status.
Select View All.
Go to 3rd step, select Export, then you have the error.
It is limitation that xml maps with nested one 1:n relationships cannot be exported which is mentioned in standard WIKI.
So Export functionality should be removed from 3rd step (Create and Edit Items).
Export function will be removed in later release after 1908.
