tRFC call

Former Member — Wed, 27 Aug 2014 14:23:50 GMT

Dear All,

I was trying to implement a tRFC call using the addition IN BACKGROUND TASK; as I understand that while making a tRFC call the RFC function, together with data is saved in the database of the AS ABAP with a unique TID & I thought that we can view the TID using the transaction SM58. But to add to my surprise I could see nothing, can you please elaborate the possible reasons for this?

Well I understand the following points already.

1. A function call that contains the clause STARTING NEW TASK represents an aRFC call.

2. A function call that contains the clause IN BACKGROUND TASK represents a tRFC call.

3. If a function call only contains a DESTINATION clause but does not contain any clauses like STARTING NEW TASK or IN BACKGROUND TASK then it represents a sRFC call.

One more think if you could probably put light on is what is a bgRFC call?

Many Thanks,

Tanmoy

Hello Tanmoy,

bgRFC does everything you could do with "Classic tRFC qRFC".

But it does it faaar better.

I highly recoomend bgRFC - bgRFC Programming - Connectivity - SAP Library

To summarize, here is the list of RFC options in ABAP:

(1) sRFC – synchronous RFC (DESTINATION….)

(2) aRFC – asynchronous RFC (with or without response) (STARTING NEW TASK… DESTINATION…)
(3) pRFC – asynchronous RFC over an RFC server group (with or without response) (STARTING NEW TASK… DESTINATION IN GROUP…).
(4) tRFC/qRFC – ‘store and execute later’ RFC – execution controlled by qRFC scheduler (IN BACKGROUND TASK….)
(5) bgRFC – ‘store and execute later’ RFC – execution controlled by bgRFC scheduler (IN BACKGROUND UNIT….)

Thank you,

Best Regards,
