transfer values between background programs

Former Member — Tue, 11 Feb 2014 11:07:55 GMT

Hi expert,

I start a abap program on background with statements as follows, this program will keep running if I don't stop it.

SET PARAMETER ID 'Z_PA_EAR' FIELD TBTCM-JOBCOUNT.

SET PARAMETER ID 'Z_PA_EAR1' FIELD TBTCM-JOBNAME.

MESSAGE I001(00) WITH 'this is your information set: jobname ' TBTCM-JOBNAME ' job count: ' TBTCM-JOBCOUNT.

in its job log, I got follow message:

this is your informationset retrieved:jobnameBI_PROCESS_ABAP job count:15422800

then after a few hours, I launch another abap program on background with following statement , trying to receive values from parameter ID set by above abap

program.

GET PARAMETER ID 'Z_PA_EAR' FIELD ZJOBCOUNT.

GET PARAMETER ID 'Z_PA_EAR1' FIELD ZJOBNAME..

MESSAGE I001(00) WITH 'this is your informationset retrieved:jobname ' ZJOBNAME ' job count: ' ZJOBCOUNT.

in its log, I got following message , with blank values for getting values.

this is your informationset retrieved:jobname job count:

can you please show me how to correctly transfer values between two background abap programs in this case?

Many Thanks,

Dear Zhang,

SET parameter values exist only in the runtime between sessions. Once your runtime is ended up, system resets the runtime stack. Hence SET / GET can be useful in a continous execution of programs..

In your case either you have to execute both the jobs as a sequential steps under a single job

You need to retrieve the information using tables, if not save the information in a custom table and use the same in the next job.

Thanks and Regards,

Chandra

Hi Chandra,

for first option, I can't put those two abap program in sequent steps of job, because the first abap program keep running without end. the second abap program is used to kill first abap program. so they are not run in sequence.

for second option, I don't want to create a table only for this purpose.

can you please tell me if I can use import/export to database for my purpose, if could, how to use them?

Many Thanks,

Hello,

Are you scheduling the job via SM36 or by using the option "Execute in background" in SE38.

Try using the below statements,

First program:

export iflatf to shared buffer indx(st) id '<memory id>'.

Second program:

import iflatf = iflatf from shared buffer indx(st) id '<memory id>'.

delete from shared buffer indx(st) id '<memory id>'.
