Actual Costing: Alternative valuation : "Relevant for Costing" indicator

Hi:

We are using alternative valuation in our Actual Costing

We would like to know the use of the "Relevant for Costing" indicator. (XPCP field).

Documentation said: "If you set this indicator, the results of the alternative valuation run can be used in the standard cost estimate for the material." But there is not a clear explanation in the online doc or other info sites.

How does it works? What is the exact meaning of "can be used in Standard cost estimate"?

How can we get these values from Product Cost planning?

Best Regards:

Manuel
