Configuring Display Logic

Display Logic helps us to dynamically show or hide a field. Say, on the MOM window, we want to show the Pending Discussion detail to a user who had created the MOM and we want to display the Actioned By field only if the status selected is not Clarification. If this is the need, then what shall we do? This is where ADempiere's Display Logic is useful and we would see how it is useful, shortly.

How to do it...

1. 1. Log in as System/System with the System Administrator role.

2. 2. Go to the Window, Tab, and the Field window and open the Pending Discussion tab detail on Tab.

3. 3. Enter the following logic in the Display Logic field, as shown in the next screenshot, and save it:

   @CreatedBy@=@#AD_User_ID@
   

4. 4. The values for CreatedBy and #AD_User_ID comes from the context, which you can see by clicking on the Tools | Preference menu item and then selecting the Context tab.
