Material and task list & do not belong to same company code

What causes this issue?

You want to
allocate a material to task list &V1&
or
create task list &V1& with a material.
Task list &V1& in plant &V2& belong to a different company code as the
material in plant &V3&. The plant data determines the company code.
You can generally make cross-company code allocations in a routing.
However, a company code check is set up in your system for the fiscal
year.

How to fix this error?

Select a material which belongs to the same company code as task list
&V1& in plant &V2&
or
when you create task list &V1&, make sure that the plant belongs to the
same company code as the material in plant &V3&.
