• Message text: Component piece list cannot be changed; &1 &2 already filled

What causes this issue?

Delivery request &V2& of type &V1& (for delivery component &V3& in
delivery &V4&) has already been filled.
This means that the associated component piece list cannot be created or
changed, as this will not have anyeffect on the existing content of &V2&
(type &V1&).

System Response

The activity is aborted.

How to fix this error?

Once the content of the delivery request of type &V1& has been created,
the associated componentpiece list can no longer be changed.
If you want to make subsequent changes to the component piece list, you
need to reset the delivery component first. To do this, choose
<LS>Delivery Component -> Reset</>.
You can then change the component piece list and recreate the delivery
request of type &V1& consistently, taking account of the changed
component piece list.
