Defining Fields to be Transferred 
With a central user administration system, certain fields must be maintained centrally. It may be useful to maintain additional fields locally. If you maintain fields locally, you can decide whether these fields should be automatically redistributed (Redist.) or not.
For a list of fields whose distribution parameters you can set, go to the Implementation Guide and choose Cross-Application Components ®
Distribution (ALE) ® Standard ALE Business Processes ® Standard Business Processes ® Central User Administration ® Set Distribution Parameters for Fields (Transaction SCUM). By choosing Next page, you can display any additional fields. Choose additional tab indexes so that you can also maintain the parameters of the other groups. To save your settings, choose Save. The settings are then automatically distributed to the dependent systems.
When setting up central user administration, you should try and set the individual field options you choose in this transaction only once. You should not frequently change the field maintenance flags.

Under the individual tabs, you can choose from among the following options (some options may not make sense for all tabs):
Global |
Data can only be maintained in the central system and is completely distributed. |
Proposal |
A default value is maintained in the central system. This value is distributed when a user is created and is then maintained locally. |
Redistribution |
Data is maintained both centrally and locally. Each time data is changed locally, this change is redistributed to the central system and from there distributed to the other dependent systems. |
Local |
Data can only be maintained in the dependent system. Data changes are not distributed to other systems. |
Everywhere |
Data is maintained both centrally and locally. However, data changes are not redistributed to other systems. |
In the last tab Lock, you have the following options to lock a user: You can specify whether users may be locally or globally locked and unlocked. For local/global unlocking, you can also choose the option Everywhere. You can also specify where a user can be unlocked following an incorrect logon.
