Batch and Split Valuated Material Several doubts

Dear Experts,

In my system Batch Management is active at the Material Level.

I have created a split valuated material. This material is "not batch managed". I have posted a goods receipt document for a valuation type.

When I display material document using MB03, batch field is filled with

valuation type? Is it correct ? Though the material is non batch managed material, why did the system populated Batch information on the material document? Please clarify? Is there document or OSS note explaining this behavior ?

Thank you in advance.
