The material cannot be created since no maintainable data exists

What causes this issue?

You wanted to create a material master record. However, there is no
<DS:GLOS.user_department>user department</> that you can create for the
<DS:GLOS.organizational_level>organizational levels</> and data
specified.
This occurs in the following cases:
If the user departments assigned to the material type or to the plant
do not match the data specified
If, when transferring data (program RMDATIND), you have not set the
<LS>Check required fields</> indicator, and <ZH>all</> user departments
matching the material type or the plant have
<DS:GLOS.required_field>required fields</> without entries

System Response

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

How to fix this error?

Check your entries and, if necessary, maintain the required fields not
containing an entry.

How can this happen?

If you transfer only purchasing data for a material with the standard
material type <LS>finished product</>, this error message appears
because this material type does not allow purchasing data.
