Symptom
In the Asset Viewer app (EAMS_WDA_NAV_OIF), when a user opens Navigator Settings, the Planning Plant field is empty and the error message "Mandatory parameter required" is displayed.
The user expects the Planning Plant to be pre-filled with a default value so that the navigator can filter orders and notifications. However, the field is blank and the user must manually enter a value every time before clicking OK.

Environment
- SAP S/4HANA Cloud Private Edition
Reproducing the Issue
- Open one of the following apps: Display Maintenance Order (Web Dynpro), Change Maintenance Order (Web Dynpro), Display Technical Object (App ID W0028), or Change Technical Object (App ID W0029).
- From the source app, navigate to the fiori asset viewer.
- Observe that the asset viewer requests the user to maintain the Planning Plant manually, rather than auto-filling it from the source object.
Cause
The Planning Plant displayed in Navigator Settings is a user-specific personalized value, stored in table /PLMB/NAV_SETVAL (NAV – User Specific Navigator Setting Data).
The value is not derived from the technical object's master data (e.g. equipment or functional location Planning Plant field). It is read exclusively from the user's personalized Navigator Settings record in /PLMB/NAV_SETVAL.
If no record exists for the user in this table, the Planning Plant field is empty when Navigator Settings is opened.
Resolution
To save a default Planning Plant for a user, proceed as follows:
- Open the Asset Viewer app and navigate to any technical object
- Click Navigator Settings in the top toolbar
- Enter the desired value in the Planning Plant field
- Check the "Personalize Values" checkbox
- Click OK
The system confirms with the message:
Navigator Settings values are personalized for user [user ID]
The Planning Plant value is now saved in table /PLMB/NAV_SETVAL under VARIANT_NAME = NAV_DEFAULT for the user. From this point on, the field will be pre-filled automatically each time Navigator Settings is opened.
