Authorization error in posting IDoc
I have completed configuration of File to IDoc scenario. When File adapter has picked up the file from FTP server, the message is processed with outbound error.
To find out the error occured at the outbound side, I ran the transaction 'SM58' which explained that XIAFUSER does not have authorizations to post the IDoc to destination system. Can somebody provide what authorizations should be given to this user to facilitate the processing of message.
In another instance the same error has resulted but notifying the different user. This time WF-BATCH does not have authorizations to post the IDoc to destination system.
As per my understanding there should be some system configuration where you have an option of specifying the user for posting IDocs to destination system.
Please confirm whether my understanding is correct and also let me know the where it is done?
