Value adjustment document &1 &2 &3 not yet approved

What causes this issue?

You want to enter a value adjustment amount for the earmarked fund
&V1&, item &V2&. However, there is no approved value adjustment (&V3&)
yet for this document.

System Response

The system does not allow the entry since otherwise several value
adjustment documents would be in the approval procedure at the same
time.

How to fix this error?

Either wait before entering the value adjustment until the document
&V3& is approved or change the value adjustment amount &V3&.
