Performance tunning -Help needed

[Former Member]

Hi ,

I had one ZEE program which has 25 files as input file (input data's . Here the logic of the program is as mention below.

1.initializition .

2.get_file_names.(All 25 files name is get in the same perform )

3.write_job_log.

4.open_files.(Open 25 files at a time )

5.read_surr_ctl_file.

6.load_internal_tabs.( Load 25 files data to ITAB )

7.create_edi214_tables.

8.process_ekko_ekpo.(Proces the ITAB data at the time.)

9.refresh_internal_tables.

Here they are openning 25 files , then loading all 25 files to ITAB and processing all the loaded datas.

When this progarm is schedule in background it takes 1.25 hrs to complete the process .

I need to tune this program which ever possible way.

My thought and analysis in this program is -> This performance problem is due to like openning 25 files , then loading all 25 files to ITAB and processing all the loaded datas which may hit the performance . Kindly let me know you IDEAS and experence on this issue . This program is having 10000 lines of code ..

Regards,

Veera
