If mobile applications are assigned in a back-end system using a role, role synchronization (WAF_DEPLOYMENT_FROM_ROLES) creates a user with the same name without authorizations and with an initial password for each user with this role who does not yet exist on the SAP NetWeaver AS. This is only true for the back-end systems that exist in table MEMAPPDEST as an RFC connection (see Changing Synchronization Container Processing).
You must create user group MESYNC so that you can later find this user and assign it the required authorizations. All automatically created users are assigned to this group. If the group does not exist, the users are not created.
1. Start transaction SUGR.
2. In the User Group field, enter MESYNC and choose Create User Group.
3. Enter a description of the user group in the Text field.
4. Choose Save.
All automatically created users are assigned to group MESYNC. You can find these users with transaction SU10 and assign them the required authorizations together.
