Message text: Function cannot be used for lower-level materials
What causes this issue?
In material aggregation, you tried to include, exclude or reset this
line for material &V1&. However, this is not possible, since &V1& is a
subordinate component of one or more materials.
This can also occur if a material and the associated subordinate
material are aggregated in one line (for example, in the case of a
discount in kind).
The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
System Response
The system does not allow you to include, exclude or reset this line.
How to fix this error?
You can include, exclude or reset this line indirectly by including,
excluding or resetting the corresponding superior material.
If a material and its subordinate material are aggregated in one line,
expand the line by the higher-level material.
