Hello,
Split Valuation does not mean that you can define it as per the storage location configuration.
It's different concept.
Split valuation enables you to valuate substocks of a material in different ways
(for example, according to external procurement or in-house production or by batches).
Next, in your case, it is very diffcult to understand that what is actually happened.
So, I request you to Pl again check all the setting and the trasaction you made.
And then give us the complete details of configuration.
We will definitely give you the solution of this happening.
