Automatic Refresh of Template

Question

I have a user exit variable on 0MATERIAL with "Restriction of Values Required by User".  I derive the list of materials for this variable from certain "pre-defined" material groups.  I use this user exit varible in a planning folder.  So, when the user executes this folder, he/she will be asked to select a unique material from the "pre-populated" list.  But once the user selects the material, the template is not automatically refreshing to get the data for that material.  The user needs to press the "Refresh" button to pull the data.  Is there a way to "Refresh" template once user selects his/her choice of material?
If a "User Entry" variable is used instead of the "User Exit" variable, the template automatically refreshes.  Our users are accustomed to this behavior and they want the template to refresh automatically when they select the required material on the "user-exit" variable also.  This problem is similar to "variable refresh in BPS templates" and is discussed in the following posts.  None of them are conclusive.  Please help.

Hi Sameer,
I had a similar problem in the past & i resolved by making sure buffer call is is set to initial for variable change by user.
I'm not sure how your exit function looks for the variable, but if you are using "l_buffer_call",
make sure it is set to initial.
If the exit function has following line
l_buffer_call TYPE boole-boole VALUE ''.
layouts gets refreshed for each varibale change by user.
But, if exit function has following line
l_buffer_call TYPE boole-boole VALUE 'X'.
layout doesn't get refreshed for each variable change by user.
Hope it gives some insights.
