Different batches and/or valuation types are not allowed

What causes this issue?

The <GL:batch>batches</> and/or <GL:valuation_type>valuation types</>
&V1& (stock batch) and &V2& (master batch) have different values.
However, variances are only allowed if the serial number does not
comprise a value for the stock batch (for example, if it has just been
posted from the stock). In this case the master batch can comprise the
batch of the last inward movement (just before the serial number is
posted).

How to fix this error?

Because the stock batch has a value in the present case, the batch of
the last inward movement is not allowed to deviate.
For this reason, make sure that both values are the same.
