The product cannot be created since no maintainable data exists

What causes this issue?

You wanted to create a product master record. However, there is no
user department that you can create for the
organizational levels and data specified.
This occurs in the following cases:
If the user departments assigned to the product 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 product type or the plant have
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 product with the standard
product type <LS>finished product</>, this error message appears because
this product type does not allow purchasing data.
