Dunning

Hi everybody!

Can anyone help me about F150 - Dunning?

I'm creating a procedure with 3 levels. In the second level I need the transaction check the user and the value.

If the user is not a coordinator (for example) and the value of the document is higher than 3000,00, so the transaction should show an error message and dont't create the letter.

Do you know if is it possible by a user exit?

Thanks a lot!

Danielle.
