Do not define cross-material control cycles for crate parts

What causes this issue?

You want to define a multi-material control cycle for crate parts.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

System Response

A general Kanban quantity applies for all affected materials in
the multi-material control cycle. The system does not allows this
assignment because of the potential complications involved.

How to fix this error?

Multi-material control cycles are only allowed with material staging
indicator "1" (direct picking) and "0" (no WM staging).
If you want to define materials as crate parts, create an own control
cycle for these materials.
