SAP Note 22788 - Batch input: Creating material master data (class.)

Symptom:

You want to import classification data, that is, the allocation of an object (material) to a class and the valuation of the characteristics, by means of batch input with transaction MM01 (Create Material). This causes an error. The batch input session cannot be executed.

Cause and prerequisites

Classification data cannot be imported into the system via batch input with transaction MM01. MM01 cannot be run in batch input mode for this data.

Solution
You have to write batch input sessions for the corresponding class transactions (for example CL20).
