Procedure documentation Removing a Child System from Central User Administration  Locate the document in its SAP Library structure

Use

If a system is no longer required in the system landscape, or the central system is inactive and a user must be maintained, remove the child system from Central User Administration (CUA) with report RSDELCUA, which you can start in transaction SCUA by choosing Delete.

Procedure in the Central System

...

       1.      In the central system, start transaction SCUA, and choose Delete.

The system displays the screen Delete Entire Central User Administration. The name of the distribution model is displayed under Central User Administration.

       2.      In the Delete group box, choose the Child system option, and enter the child system to be removed from the CUA (for example, using input help).

       3.      Set the Test indicator, and choose Execute.

The system displays an overview of the data to be deleted. You can jump to transaction SE16 by double-clicking.

       4.      If you are happy with the test result, choose Back and deselect the test indicator. Then choose Execute.

The system displays an overview of the deleted data.

       5.      In transaction WE20, under Partner profiles for Partner Type LS, delete the message types CCLONE and USERCLONE for the receiving system (child system).

Caution

If there are no longer any other message types, you can completely delete this partner profile. However, you can then no longer distribute the distribution model to the child system deleted from CUA. This means that you must also perform steps 3 and 4 in the Procedure in Child System.

       6.      In the Implementation Guide (IMG, transaction SALE), choose Modeling and Implementing Business Processes Maintain Distribution Model and Distribution Views (transaction BD64).

       7.      In change mode, delete the methods for the child system.

       8.      Save your entries.

       9.      Distribute the distribution model by choosing Edit Model View Distribute and select the child system that you have just deleted in the selection on the dialog window.

   10.      Check whether the child system was deleted from CUA using the transaction SCUA.

   11.      If there are no other CUA child systems in the SAP system that contains the child system that is to be removed from the CUA, change the system user in transaction (such as CUA_PRD), by removing the role Z_SAP_BC_USR_CUA_CLIENT on the Roles tab page. If this means that the user is no longer assigned any roles or any profiles, you can assume that it is not used for any other purpose, and can delete it.

Note

As the RFC destinations that you created along with CUA may be used for other ALE connections, you should not delete the RFC destinations, but rather only remove the roles with CUA authorizations from the system user used for CUA.

Procedure in Child System

...

       1.      Delete the data for the sending system (central system) in transaction WE20.

...

Note

If only the automatically created message type SYNCH remains, you can completely delete the partner profile. However, “empty” partner profiles of this type do not cause any disruption. If other message types are still entered, the partner profile is still being used in other ways, and may not be deleted.

Note

If you have distributed the changed distribution model in the central system to the child system, you no longer need to perform steps 3 and 4.

       2.      In the Implementation Guide (IMG, transaction SALE), choose Modeling and Implementing Business Processes Maintain Distribution Model and Distribution Views (transaction BD64).

       3.      In change mode, select the model (such as CUA), and choose Delete.

If the system does not now display a dialog box asking: Model view CUA may not be changed in this system. Delete CUA?, perform the following steps:

                                                  i.       Call the Edit model view dialog screen by double clicking the model.

                                                ii.       Change the Maintenance system to the local system name (such as PRDCLNT324).

                                               iii.       Choose Continue.

                                               iv.       Choose Delete again.

Confirm the system query Model view CUA may not be changed in this system. Delete CUA? with Yes.

       4.      In the child system, change the system user (such as CUA_PRD_324) in transaction SU01 by removing the role Z_SAP_BC_USR_CUA_CLIENT on the Roles tab page. If this means that the user is no longer assigned any roles or any profiles, you can assume that it is not used for any other purpose, and can delete it.

Note

As the RFC destinations that you created along with CUA may be used for other ALE connections, you should not delete the RFC destinations, but rather only remove the roles with CUA authorizations from the system user used for CUA.

Result

You have removed the child system from Central User Administration. If you want to include it in CUA again, you must perform a user transfer again.
