Mrrl issue

Dear All

My requirement is like this..

MRRL tcode is creating IR no automatically , but when IR is getting created it is getting posted on

todays date means it is taking system date...

I debugged the program they are using one FM MRM_INVOICE_VERIFICATION_ERS

but there is no date option

I need to give date option in Selection Screen so that IR will be posted on that date itself..

Please help me...
