Hi All,
We are facing issue in production, where one of extraction job from R/3 to BW is taking more than 7 hours of time.
Here Data source is the customized one, and extractor structure is based on view where consists of 9 tables. Problem here the same job where used to take only 15 minutes for records 458000 but after the migration happened ( Data center migration moved from one vendor to other vendor ) and after that only the issue is there where job is taking 7 hours for similar amount of records.
We checked the same scenario in quality, where there is no issue the job is taking only 15 - 20 minutes of time.
Through the first stage of analysis we had done the trace details for long running job in R/3 , As per the trace details the job is taking its maximum time at the DB end (Which is 82.1%). In ABAP its taking 17.9% of its total execution time and in DB its taking 82.1% of its total execution time.
Maximum time taking while calling the two exits
In Exit EXIT_SAPXXX_002 its taking the time at DB end while selecting the data from two tables. At this statement took 31.3% + 10.5% of total execution time.
In function Z_BWEX_DS_MD_ZBW_XXX taking 40.3% of total execution time at the fetch statement.

I tired analysing with the subset of data i.e. by limit the data being processed by restricting it but unfortunately there is no selection available.
And also will check the system performance at that time and number of available back ground work process are free.
Don't know what exactly that cause the issued after the migration happened. We have raised an OSS message for that.I'm trying to understand why/what is use of the first exit, where two expensive select statement on two tables meant for ?
Note: Here our BW system DB is HANA , and our R/3 is oracle DB
Can you guys help me with the issue.
Thanks in advance for your help
