SAP Note 28571 - Why are no requests deleted in SE06?

Symptom:

The customer wants to reset the number range in KTW or WBO, or wants to discard other requests.

Cause and prerequisites

• Limited number range for requests.

• Reset the test system, and so on.
  

From Release 2.1G onwards, the deletion of requests in SE06 is no longer available.
Why is this?

• Prior to Release 2.1G practice had shown that as a rule too much information was being lost.

• Consistent deletion is not possible, because for example, references to deleted requests remain in the version database and also in other systems.

• To avoid inconsistences in the transport system, all files and file

• entries for the requests to be deleted would have to deleted too.

• The log files belong in this catagory too.

• With the deletion of requests, an important element of the history of the system was being lost.

• Even for a database copy, it is not sensible to delete the requests copied at the same time. Requests belong to the Customizing of the system and therefore are needed for copying.

• Fresh systems without a past are created by installation. Customizing can be carried out via client transport relatively quickly.
  

Solution
You can delete requests that have not been released using Transaction SE09 (from 3.0) or SE01 when they have originated in the system.
When the number range of a development system is exhausted, we recommend the reconstruction of the system (new installation and system copy) using another name.
