System users are reFuired for the internal communication of the systems in an AL group. (hese

system users- defined in the target systems- are entered in !"C destinations in the calling systems.

ote o )i&ense fees app)' to these s'ste% users#

(o simplify the maintenance of system users- use the follo*ing naming con6entions:

7n the central system system A)C/- the naming con6ention *ill be CUA70s'ste% $. (hissystem user is used in the !"C destinations from child to central system. Dith this naming con6ention-

*e need to create the system user in system A)C *ith name: CUA7ABC

7n the child systems- the naming con6ention CUA770S'ste% $70C)ient. (hese system

users are used in the !"C destinations from central to child system. Dith this naming con6ention- *e
