Create an RFC User in SAP
Many tools associated with SAP rely on Remote Function Calls or RFCs. A great example of a tool that utilizes RFCs is the automated obsolescence determination tool.
RFCs don't operate in a vacuum of security; they require an account in SAP with appropriate permissions. It may be that the BASIS team or security team may not know what it means to make an account "RFC-capable". This whitepaper is a primer for the creation of RFC users.
Start with the User Maintenance transaction. It's in the SAP Easy Access menu system under Tools→Administration→User Maintenance→Users. Alternatively, the same transaction can be accessed using the transaction code SU01.
Type in the name of the new RFC user and then click the New button. For the purpose of this whitepaper the user name "rfc_user" will be used.
Under the Logon data tab select the "Service" radio button. This tells SAP that this user will not log in using SAP GUI, but instead performing Remote Function Call as part of an external system.
Under the Profiles tab add the S_A.SCON
profile. This gives the user the permission to log into SAP and perform RFCs.
Click the "Save" button. When the message appears the RFC user account has been created. All that is left at this point is testing.
