HI All,

I'm facing the below issue in master planning planned orders

created items with BOM setup and item coverage ( item coverage is setup to create planned transfer and production orders ) 

scheduled master planning batch job ( regeneration method )  with a query which creates planned transfer and production orders based on item brand type , which is working fine , all the orders are getting generated under a master plan

however i'm facing a issue , system is creating planned purchase orders for other items under the above master plan ( which does not belong to the brands defined in MPS query )and  which does not have any BOM setup or item coverage 

please provide me some pointers on how to restrict to create planned purchase orders
