Generally in sap standerd It is possible to do pgi Only in the lost monly
But if we want to create PGI More than One month back We have to check some perameters
we have to check on perticuler date stock was available ?
we have to deactivae availbility check in VOV6 ?
And in VOV8 we have to remove Lead time in days and Remove proposed delivery note ?
Theese are Standerd settings and Final IMP THIS IS
MMPV_READ_NOTE By using this Functionolty by ABAPERS May be in your business they might have opend Physical periods
so just check it again
