LTP MD02/MS02 Purchase Requisitions

Experts,

If I run MD02 I am able to create purchase requisitions & scheduled lines via MRP control parameter on input screen.

If I use MS02 I do not have these option. As result SAP shows planned. orders instead of purchase requisitions & scheduled lines. The required information are all sitting in the planned order.

So my question is:

Is there a way to show in LTP (MS04) purchase requisitions & scheduled lines items instead of planned orders ?

Thanks in advance
