Requirement wherein I want to call two queries in parallel using ABAP Prg

Question

We are using RSCRM_BAPI to run a query in background and write the results to a table. We later read this table and create a file. I have a requirement u2013 wherein I want to call two queries in parallel using an ABAP program.
For our discussion assume:
1) Program : ZCALL_RCRMBAPI  is a program that calls RSCRM_BAPI in background and takes the query name as input
2) Program: ZMAIN_PROGRAM  this is the main program
The requirement is to call the ZCALL_RCRMBAPI in a loop. Also within the loop call it in parallel. Basically we have an ODS that stores ; FISCPER. So I call the two queries for a list of FISCPER.
ZMAIN_PROGRAM - A program that reads a table (ODS ) in our case and call the two programs in a loop and both should run in parallel .
Now if it was sequential u2013 it was easy u2013 I would just say
Loop at L_T_FISCPER .
Update Z_FISCPER with L_T_FISCPER-FISCPER u201C Assume Z_FISCPER is a Z table . The VARIABLE in the query Q1 and Q2 use a customer exit to read this table.
A)       SUBMIT ZCALL_RCRMBAPI with P_QUERy = Q1 and return .
B)      SUBMIT ZCALL_RCRMBAPI with P_QUERy = Q2 and return .
Endloop .
Question: How do I make these calls in parallel u2013 yet retain control in the main program?
A)       SUBMIT ZCALL_RCRMBAPI with P_QUERy = Q1 and return .
B)      SUBMIT ZCALL_RCRMBAPI with P_QUERy = Q2 and return .

Answer 1

Instead of RSCRM BAPI you can use the RRW3_QUERY_VIEW_DATA function module for greater control over program execution...
