SAP BW Query: Automation test setup, step-by-step

Hi, community!

In the post I’d like to share my experience and thoughts about automation of testing BW(Bex) queries. During upgrade/migration projects customer wants to be sure that its BW(Bex) queries return the same result before and after upgrade ceteris paribus. It’s not always true because SAP as a vendor make modification in the standard function modules, classes and so on, used in BW(Bex) queries. Even if we know wht was changed in recently installed service pack, the question “How it influence particulary to the set of critical BW(Bex) queries?” is open. That’s why automation of testing BW(BEx)-queries can guarantee that you never miss unaffordable changes. And it saves project costs, because it will take your only a couple of minutes to perform the comparative test and find out the problem areas.

The blog consist of 2 parts: summary and detail.

In the summary part I post the only one screenshot. It shows final screen with test results: Bex-query result set before changes [in the system / in the query data /  in the query logic or smth. like that] and after changes. Red status of cells means that comparion fails: query executed “after changes” (upper part) produces different result in comparison with query executed “before changes” (lower part). And changes are highlighted!

In the detail part I post series of screenshot for “step-by-step” to set up most part of relevent settings

Firstly, decide what query you would test. Prepare their technical names and variable values for their selection screens. Then run tcode: RSRTRACE and activate trace for ther user

Now you can start recording query results to be compared after changes. During my investigatoin the best way to record query results is by using tcode RSRT with HTML-presentation. Unfortunately this type is not relevant for BW4/HANA. But other types of presentation like list, BICS are difficult to compare. Try’em by your own and I you can upderstand what I mean.

Then return to RSRTRACE and stop tracing. Lets review trace results

In the tab “Ref.Data” you can see recorded results of query execution (in me example I recored 2 bex queries, that’s why 2 records in log you can see on previous slides).

Here the recorderd result

Then I made some settings for automation our testing. I created test package with the trace record

and test job for execution test package next time, after some changes in the BW system

You can see results of job execution by clicking on reporting icon in the grid (see above picture). Then you drill into separated BexQuery with Job Log (see filter on Log GUID field) which stated that everything was OK (Message Type S)

Next I made some changes in the BW system which may lead to Bex query result changes. And execute the job immediately (again)

after job finished I went to job log and drill into BExQuery with job log again

Error status in Message Type!

So we need to make detail investigation next! Go to CATTS TRACE and execute trace record again

We see error status which means that save results are differ from last recorded

Go to detail information and see.. the same slide as in summary oart og the blog
