Two PIR's getting created for forecast released in 3rd bucket

Hi Experts,

For few SKU's we are releasing the forecast in 3rd bucket of a month. We have noticed that 2 PIR are getting created.

If forecast is released in the month of July , what ever the future months with 31 days in a month 2 PIR's getting generated and 1 PIR for calendar month with 30 days.

Its vice versa if released in a Month which has 30 days.

If length of Distribution function is changed to 31 from 30, The problem occurs in revers i.e for 30 day cal month 2 PIR's getting generated.

TIA
