credit control and transfer order for delivery

Greetings !

We have an issue with credit control and delivery and WM. I mean everything works just fine except one thing. We'd like to make system to proceed with credit control when transfer order for delivery is created (LT03). In VOFM Iu2019ve found routine which is responsible for checking current status of credit control but it doesn't update it what is our need. Is there any reasonable solution to our problem ? please help

regards
