Multiple business roles and org data determination

Hello together,

we are having an issue with the organizational data determination. Some users have multiple business roles in different sales organizsations. This means, they are assigned to several units in our org modell.

This users can select the business role after the login screen. But this selection doesn't affect the org data determination (rule: ORGMAN_12).

For example. My user is assigned to 4 different org units. After the login i select a role. In debugging i can see this role, but the system selects only the first role and not the role i've selected after the login.

Is there any other rule which follows the select business role? Or can i assign one user only to one unit?

Best regards

Sascha
