Diagnosis
You are attempting to write &V1& to the material master as the inventoryprice. However, the system has determined that the valuation unit in thematerial master was changed after the price was updated to the pricetable.
The new price in the price table was therefore created or calculated onthe basis of a different valuation unit than that currently defined inthe material master. For this reason, this price cannot be usedas the inventory price with the new valuation unit.

System Response
The system cannot change the inventory price and consequentlycannot revaluate the inventory.

Procedure
Create a new standard cost estimate or enter the priceagain.
If you created a new standard cost estimate, update theprice for the material.
Change the inventory price.
