Hi Olivier,
We cannot delete the association of the Object that you have made with the BROWSE RESOURCE (ID: BROWSE_PROJMGR ) lookup
And also making direct database updates is not supported and could cause issues because changing the associated lookup will be in conflict with any data already saved on this attribute for each instance record.
The best recommendation is to create a new attribute associated with the correct type of lookup.
Then you can query the old attribute or put it next to the new attribute in the UI and update it through the UI or if there are lots of records to update, you can use XOG to read out all the records and manipulate the XOG file to fill in the correct value for the new attribute.
And also we cannot assign IDEA Managers to Action items because this is working as Designed.
CA PPM Process Action Item assignees functionality is expecting to use the internal record ID for a Resource record, stored on the SRM_RESOURCES table, not a user record ID.
Where in the Idea Manager attribute is defined using the BROWSE_PROJMGR lookup.
This dynamic query lookup uses the CMN_SEC_USER.ID as the hidden key.
This is why the Idea Manager attribute is not available for selection on the process.
So, I request you to raise an Enhancement so as to see the Idea manager in the Action item Assignees.
Thank You.
Regards,
R Preethi.
