Parallelization is not happening using asychnronous RFC in a function module

Question

A BW data source ZTEST
has been created based on a function module ZTEST_FM to pull the
data into BW system from R/3.
(Have checked the parellel jobs running in SM66 transaction).
Inside the function module, an RFC function
module ZTEST_RFC1 has been called asynchronously to implement the parallelization
to improve the data extraction time into BW system.
Note: In this scenario asynchronous
RFC is used to implement the parallel processing.
The logic in the function module is as follows.
Function module ZTEST_FM Logic:
Fetch data from HRP1000 table into an internal table IT_HRP1000 for
OTYPE = ‘TN’.
Loop at IT_HRP1000 into work area (WA).
Call the RFC asynchronously by passing OBJID,OTYPE and ENDDA,
Calculate SOBID which is the required output field from the RFC
function module.
Populate the results into final internal table E_T_DATA.
The output structure contains the following fields.
OBJID
BEGDA
ENDDA
SOBID
Could you please give us some suggestions, to implement the parellel processing using asychronous RFC in this scenario.
Would appreciate your help.

Answer 1

Your RFC call looks correct. For collecting the result you will need to code the callback routine Write_E_T_data. Inside the callback you can use the statement
RECEIVE RESULTS FROM FUNCTION ZFHLS_EX_TNM_ACADEMY_RFC1 IMPORTING <parameter list>
to retrieve the calculated result. For the declaration of the callback routine I recommend
FORM Write_E_T_data USING iv_name TYPE c.
The parameter iv_name containing the name of the RFC task turned out to be mandatory in my tests.
