User exit in tran PPOM/ppom_old

Dear All,

We have the requirement to restrict the operations like delimiting to be allowed only for current and previous months based on the date user is going to enter, operation involving date beyond curr and prev should not be allowed.

Is their any user exits where we can do this, We have done this for PA30 for few infy types so looking on the similar lines for tran PPOM/PPOM_old.

Regards,
