Remove field relationships

Question:
 How can I remove relations that are blue from the relations window?
 

Answer:
Relationships that are shaded blue in the relationship window are field relationships.

 

You cannot delete these via the right mouse button or the delete button; you can only delete them from the assigned field on this process step.

Make sure that the field window is visible via the Layout tab (place a check mark in front of Fields)



Go to the subject on which the relationship is located and open the field window here

Notice in the screenshot above; that on the process step Sales in the assigned field set 'Process Data' the Sales Manager is listed as Owner.
Now right-click on the Owner field and choose 'Return to default'




 

then this relationship will no longer be linked in the field and will disappear from the relationship window:
