Hi Raj,
Mentionin g the solution what I understood(might be not correct)
How you are passing the demand in MRP. I think PIR will solve your problem. You can upload the required material month wise ( I mean whenever you required the material). MRP will provide the proposal on those months.
You create PIR for July also.
Please let me know the further concern and whether my understanding is correct.

Krishnendu.
