Check if the Sales Order is credit block.

Hello Everyone,

I have a requirement related to third party sales order and delivery. In the first system, a sales is created and then the PO gets created. Upon the creation of the PO a IDOC gets generated. The inbound IDOC in the other system triggers and a sales order gets created. The requirement is that if sales order in the first system is on credit block then automatically the sales order in the second system should go on delivery block.

The solution that I have thought is that when the IDOC gets created after PO generation there itself add a flag to IDOC in case of credit block in sales order. BUT HOW TO CHECK CREDIT BLOCK of the SALES ORDER IN THE CUSTOMER EXIT?

Any help is appreciable.
