Need to make "opening date" mandatory in SRM RFx Header Screen

Dear All,

Working for SRM component "/SAPSRM/WDC_DODC_RFQ_H_BD" there is field "OPEN_DATE_TIME" which i need to make it mandatory .

There is standard config to do the same but its not happening through that is there any way I could do the same.

I have also tried to enhanced the application and made it mandatory in MODIFYVEW method and given the error message also but it allowed the RFx to get publised even tough the date is not entered.

Really appreciate the same if anyone has come across such requirement.

Thanks
