Only one PR created in time phased

I am running time phased planning(R1) with lot size EX. Planning cycle - Tuesday and Wednesday. No delivery cycle.

I have PIRs created for current date+30 days.

After MRP, ONLY ONE Purchase Req created and that is only for first planning cycle. System is not planning the PIRs after first planning cycle.

Note: In config of mrp type- total requirement indicator is checked.

Thanks for your help.
