in current scenario when we check SIP procured in a period, only those records are visible where sip start date is less than current date.
so for ex. sip is registered on 15th Oct & SIP start date is 01st Nov.
This entry will show in MIS only after 1st nov.
Now a days we register sip thru NSE/MFU where SIP is registered immediately even if date of 1st installment is after 1 month.
So, all such SIP imported thru mailback should show inMIS even if start date is yet to come.
