Issue with ALE configuration for creating the idoc for Purchase orders

Hello,

I am trying to send the purchase order through message type configuration using ALE.

I am using idoc ORDERS05, message ORDERS, Process Code in Partner profile ME10.

In NACE transaction for the Application EF, Output Type NEU the ALE Configuration is done for Program RSNASTED Form ALE_PROCESSING.

I have done ALE distribution using BD64.

Now the problem is that when an order is created or changed in the message output of the PO I am seeing the status as yellow i.e.not processed.

In NAST table, the entry is there but on executing RSNAST00 nothing happens.

Please provide me the pointers to solve the given problem.

Regards,

Mayank
