SLT Replication - RFC user

Hello Experts ,

We are configuring SLT replication with Sourcesystem ---> SLT System ---> HANA DB .

I have read some where that the RFC user on source system must be of type --> DIALOGUE , Is it mandatory that the RFC user must be DAILOGUE type .

But SAP document says ..It must not be DICTIONARY User type .

Please advise what is the correct RFC User type on source system for SLT config replicaiton .

Thanks
