SAP Error Message - Details

• Message class: TR_AUSL - Software Delivery Composer Messages

• Message number: 190

• Message text: Supplement change piece list is not modifiable; &1 &2 is already filled

What causes this issue?

Delivery request &V2& of type &V1& (for delivery component &V3& of
delivery &V4&) has already been filled.
This means that you cannot create or change the corresponding
supplement change piece list since this no longer influences the
existing contents of &V2& (type &V1&).

System Response

The action terminates.

How to fix this error?

After you have generated the contents of the delivery request of type
&V1& you cannot make consistent changes to the supplement change piece
list.
If you want to make subsequent changes to the supplement change piece
list, you must reset the delivery component. Choose <LS>Delivery
Component -> Reset</>.
You can then make changes to the supplement change piece list and use
it to consistently re-create the delivery request of type &V1&.
