XML tree Payment Medium Workbench Enhancement

Hi Experts,

I am using CGI_XML_CT as a payment tree. I wanted to enhance ReqdExctnDt node in order to push for the Value date instead of the posting date.

However I've just seen that the date information was filled it with the structure FPM_CGI instead of the structure FPAYH - and refers to the field DUEDATE_CGI.

I would need to understand how this field is filled in by the Payment Medium Creation Program, but do not find it !!! 😠 I would expect somehow that FPM_CGI is filled in based on FPAYH structure...

Thank you all for your support
