&1 successful and &2 incorrect goods movements

System Response

The system reports back as incorrect only those goods movements that
could not be carried out.
If the goods issue or goods receipt for one of the deliveries selected
has already been posted by way of the subsequent function <LS>Post
goods issue</> or <LS>Post goods receipt</>, the corresponding delivery
will be reported back as successful.
Note that for partial goods receipt the posted items and not the posted
deliveries are counted.

How to fix this error?

If the posting was executed in the 'Background process' mode, you
should check the error log to find out the cause of the incorrect goods
movement. Alternatively, you can also let the posting transaction run
in 'Foreground process' or 'Foreground for error' mode. Make the
necessary settings in <LS>Settings -> Subsequent functions</>.
