Outbound Idocs for PO - PORDCR1 remain in status 30 (Ready for dispatch)

Hi All,

We are using PORDCR1 Idoc to send POs from ECC to SNC. After saving the PO, an Idoc is trigerred but it remains in status "30" - ( IDoc ready for dispatch (ALE service) ) inspite of having the Output Mode in Partner Profile as "Transfer Idoc immediately". The Idoc gets sent only after manually processing it using BD87.

My queries are:

1. Should we run the program "RSEOUT00" even for the above Partner Profile setting ?

2. If so how to ensure the Idocs are triggered immediately after the PO is saved / changed in ECC?

Regards,

Bharath
