Answer» Some of the SALIENT features of tRFc are:
- tRFC guarantees that a called function module is executed in the target system exactly once.
- All tRFC calls terminated with the statement COMMIT WORK belong to one LUW (LOGICAL Unit of Work). Each LUW automatically receives a transaction ID.
- Within an LUW, all function modules are executed in the target system in the sequence in which they are called in the SEND system.
- tRFC calls with the addition AS SEPARATE UNIT map a separate LUW each in the target system. Such a sub LUW contains exactly one tRFC call and is processed independent of the actual (superior) LUW. This sub LUW receives its own transaction ID.
- If within an LUW several DESTINATIONS are used, all tRFC calls that belong to one destination also form a sub LUW. However, SINCE this bundling happens only internally, there is no separate transaction ID assigned to the sub LUW.
