EDI1 Condition type not determined automaitcally in ORDERS process

Hi Experts,

We are in the process of creating the Sales order by receiving EDI data from customer and converting in to IDOC format and trying to create the sales order. While executing the ORDERS IDOC message type sales order is getting created successfully. But Condition type EDI1 is not getting activated even after maintaining the value in E1EDP01-VPREI.

During foreground mode, if we maintain the EDI1 condition type manually then, its accepting without any issue. But during IDOC process its not getting added automatically.

Please give your suggestion on this.

Warm Regards,

Nag
