PA30 User exit for Creating work tax area

Question

Hi all, 
I have a requirement to create a work tax area for personnel with allocation percent is allowed more than 100% for two particular tax areas. 
For this I tried to use the user exit EXIT_SAPFP50M_002. In that user exit I have written the condition if the tax area is one of the two areas and the allocation percentage is greater than 100% then skip the validation it is doing currently.  But this user exit is not called when I run the program. I ran in the debug mode to see if it is called. But it is not called.   
Currently if I enter allocation percentage greater than 100% then it will fire a dialogue message box saying “Work percentage cannot be greater than 100% Change existing records”.
So I am wondering if it is the correct user exit to use.  Can you help? 
Thanks for the great help.

Hi sobhan,
1. ideally, this is the correct exit.
2. for all infotypes, on saving,
   this is called.
3. to check,
   just give some MESSAGE statement
   (without any If or without any logic
   and without any checking of infotype)
4. From that we will come to know,
  if this is really getting called or not.
5. Also make sure, the PROJECT (CMOD)
  is activated for this enhancement.
