Reciever User Authorization in RFC

Hi All,

In my outbound idoc scenario,earlier we were using a Receiver USER ID( in RFC) with SAP_ALL. but due some reasons , the SAP_ALL authorization is removed for this user.

Please guide me what are the Tcodes to be assigned to this user for a smooth transferring of Idoc. As in sender system the Idoc program is a Custom program ..do i need to provide this tcode also( i doubt this bcoz this Tcode will not be avlbl in receivers system).

any help would be grate full.

regards,
