SAP Error Message - Details

• Message type: E = Error

• Message class: TR_AUSL - Software Delivery Composer Messages

• Message number: 302

• Message text: Completion piece lists not allowed (delivery component &2, in &1)

What causes this issue?

You cannot register completion piece lists (such as &V3&) as upgrade
piece lists. You can only register the change piece list of the
delivery component &V2& (in delivery &V1&) as an upgrade piece list -
after you have included the completion piece lists.

System Response

The function terminates.

How to fix this error?

Include the completion piece lists of the delivery component &V2& (in
delivery &V1&) in the change piece list. (To do this, go to the
Software Delivery Composer and choose <LS>Utilities</> ->
<LS>Completion piece list</> -> <LS>Merge all in change piece list</>.)
Only then can you register the change piece list as an upgrade piece
list.
