Changing Material Price in MR21.

We have some materials with Split valuation.

Valuation type-1 (New)

Valuation type-2 (Expensed)

The Material in material master shows Moving Avg Price as 100 for Valuation Type(New) and

Moving Avg Price as 0 for valuation type(Expensed).

But in Material master when i dont select any valuation type it shows Moving Avg Price as 50.

I need to change the price for this material.

When I try to modify the price in MR21,it asks for valuation type and Iam able to change the price for

either valuation type(New) or valuation type(Expensed).

How can I change the price of the material that appears when no valuation type was selected in

the Material master.

It would be great,if someone can give me the solution for this.

Apperciating ur immediate response.
