MD04 - MRP element data without value

Hello,

I have the following scenario:

In a Finished part number, there are 2 records in MD04 in the MRP element "SchAgr" but the MRP element data is in blank.,

When I push the glass bottom to display I get this:

Total reqmts SD SchAgmt Requirement type 050 = Warehouse consumpt.

AllIn 1 Consume planning with assembly

Rec./reqd quantity 1,656 PCE Planned dates 06/26/2009

but When I tried to edit it, I got this error:

Selected function cannot be used for the element

Message no. 61111

How I can delete those records? That are not needed and it is affecting the planning of the other levels since it is requesting materials.
