You specified different levels of the article hierarchy

What causes this issue?

You specified level &V1& of the material hierarchy for the query in
Customizing for data retraction, but level &V2& in the selection (via
selection screen or from the item data).
You can only use the level of the material hierarchy (and thus only
nodes from this level) that is specified for execution of the hierarchy
in Customizing.

System Response

This message is also displayed (with selection level "0") if you do not
specify the material hierarchy at all, either explicitly through the
selection criteria or implicitly through the item values (also see
<DS:SIMG.WRF_AT_0003>Enhancements for Allocation Table Types</>).
