Anyone knows how to link up the data on a custom logical unit to the PM_ACTION_ROLE table? In IFS10, the PM_ACTION_ROLE represents the WorkTask, and there are additional tabs below this level such as WorkTaskSteps, Resources, etc. 

If I create a new tab on this level, I am not able to add a record for the Primary Key and Child Key. If I add the custom tab on a higher level, then it is possible to add the primary/child key. So my question is, is there a workaround for this?
