Extra planned orders generated though there are sufficient Purchase orders

Hi

For a component material system is generating extra planned orders though there are sufficient purchase orders to meet the requirement.

When i check the pegged requirements for the planned order it gives a message Order xxxxxx(purchase order) possibly contains recursive BOM components

There is no recursiveness defined in the system.

Below are the MRP settings for this component.

MRP type: PD

Lot Size: EX(lot to lot) min lot size is XXKG

Availability check --- 02 (individual requirements)

Please help me in understanding the reason
