Valuation price of component & in plant & is zero

What causes this issue?

You want to post a goods movement for a structured material. In breaking
down or combining the structured material, the system determines the
cost value in relation to the retail value.
It uses the current valuation price (standard price or moving-average
price) of the components as a basis.
This error occurs due to one of the following reasons:
The valuation price is zero: If the current valuation price of a
component is zero, the system cannot carry out the calculation for the
material.
Rounding issues: The structured article may contain a component whose
proportion on the complete quantity and amount is very small. The
valuation of this component is calculated based on the valuation price
of the header - if this calculation leads to a further very small value
such that the rounding of it leads to zero, the system cannot carry out
the calculation of this material.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Check the current valuation price (standard price or moving-average
price) of material &V1& in plant &V2& in the accounting view of the
material master. If the valuation price is zero, carry out a price
change for the material. (revaluation at cost, transaction MR21).
