BDC Recording - Make a field required

Question

Dear Experts,
We are using a BDC recording to call MIRO and send it to an agent via workflow using a z-table.
The customer wants the baseline date on this recording grey'ed out and the business area field required.
The baseline date is on the "PAYMENT" tab of MIRO and Business Area on the "DEATILS" tab. 
I have created a screen and transaction variant a year ago and assigned it to the t-code, but now with the BDC calling MIRO for the INVOICE Scanning project, these fields can be overwritten and left out.
How can I do it via BDC?

Answer 1

You could create a on-submit pl/sql validation on 'p2_estim_val'. The validation code will return a failure if the value of p2_estim_val is not specified if the value of p2_reason_to_scap_sell is non-null
The validation code could be something as simple as
if not :p2_reason_to_scap_sell is null and :p2_estim_val is null then
   return 'A value is required for p2_estim_val';
end if;varad
