bw modeling tools.

It has been very quite at the moment.Because nothing spectecular is happening in the Analysis Office world. SAP released Analysis Office 2.7 SP5. I still hope they get Analysis Office 2.8 back on track and without so much problems as they have today.  But back to topic.

In my project I have now the opportunity to build SAP HANA Calculation Views. We use Calculation Views to combine two different Advanced DataStore Objects. First you have to set the parameter External HANA View in the setting of your ADSO. When you activate this setting a SAP HANA Table is created which you can use in a Calculation View.

In my current project we run into an issue that we have to match navigation attributes from one ADSO to an infoobject of another ADSO. The old feature of a MultiProvider was to Identify (assign).

If you want to create a Composite Provider in the BW Modeling Tools, you have to choose New >> Composite Provider in the context menu of your InfoArea or File >> New >> Composite Provider.

In my current project I created with a collegue a really cool function to analyze a string with 1333 characters. We are using a BW 7.4 SP 17 on HANA. First we have to build an Advanced DataStoreObject with a Field which has a length of 1333. For further understanding, we call the field Field_1333. As data type I used SSTRING.

At the moment it is very quiet about new blog post. This is maybe the summer break everybody talks about. ;)

I am at the final phase of my diploma thesis and have no time to do cool stuff and also SAP doesn't release Analysis Office 2.5. It is still in ramp up and nothing new at the moment.

So I could only say, my current project is a BW on HANA and I am testing how HANA SQL Script (AMDP) works and how fast we could build some stuff. First tests show a transformation with routines for 800.000 records about 1:55 minutes. The same transformation with AMDP (ABAP Managed Database Procedures) only need between 15 - 23 seconds. This is really impressive. 

So stay tuned, if SAP will release Analysis Office 2.5 and some examples with AMDP.

If you use a BW/4HANA instance, you have to use the BW Modeling Tools (BWMT) to build your data model. You could only build Advanced DataStore-Objects (ADSO). If you create a new ADSO, you have to select a BW-Project and an InfoArea. After that you have to define a technical name and a description. You could also use a template to build your ADSO.

After I started my BW/4HANA instance on cal.sap.com and everything was working, I logged on and typed RSA1. But there was no modeling tab anymore. Then I rememberd, I need the BW Modeling Tools. So I installed the latest Version of Eclipse and the BW Modeling Tools. After that I need a Project. The project is the binder for all activities in our BW system. Make a right-click in the Eclipse Project Explorer and choose BW Project.

This week the new open SAP course BW/4HANA in a Nutshell started. It is a free course. One big thing is that BW/4HANA no longer supports the good old BEx Suite. You now have to use the BW Modeling Tools based on Eclipse. In this and further posts I will go deeper into the BW Modeling Tools and what is possible and what is not possible at the moment.

If you have any questions feel free to ask or correct me ;) So let's get started.
