clearing cases need attention with AS4 energy market communication

What happens if my communication partner can’t follow all the EDI@Energy rules?

In this case our solution offers a feature called Clearing Case Management.

If, for example, your partner doesn’t use the latest encryption and signing algorithm, messages are sent to a designated clearing case inbox.

This allows you to process messages in a structured way. If clearing cases accumulate in short period of time, you’ll receive alert notifications. Also, for specific market partners addresses, you can set up custom email rules (policies) that are a bit more flexible with the compliance rules. This ensures a smooth flow of communication, even if there are minor deviations from the standard.
