Migration from SAP BO to Looker ? How ?

Hi Communauty, 

We have worked on a migration engine to automate migrations from SAP BO to Looker that could be interesting for those that engaged in such project. I share the methodology. We are implementing it at one of our customers. I would be curious to get your feedback.

Migrating universes

We will reproduce Looker's views and Explore with all the intermediate steps to delegate data merging from BO data providers into the target DB (via explore overloads). Objects are also redefined as Looker view fields and all the classification of these objects is reproduced in the target. Semantic intelligence is also converted into lookML (nested objects, aggregate aware, specific SQL, etc).

Migration of dashboards and intelligence

We obviously translates all the useful intelligence of the dashboards into lookML and recreates the links between the looks via smart filters. Each tab of a BO document becomes a Looker dashboard. Tab consistency is restored by linking them together in Looker.

Layout migration

We will translate the BO layout into LookLM respecting the organization of the components then will reproduce the different tables, sections, graphs according to the existing components of Looker.

Some further informations:

  • Dimensions and measures of BO universes will be organized in the same way in Looker.
  • BO documents will be transformed into several dashboards in Looker: one per BO report (tab), with a menu to navigate between them.
  • Aggregate Aware, dashboard variables and derived SQL are reproduced as is in Looker. 
  • The syntax of the source database is translated into the native syntax of the target DB (usually bigQuery).

Hi Théo,

I'm facing a challenge to migrate sap bo univers to looker. In SAP BO, (DFX) relationships let you connect tables and still display just one dimension when needed. However, Looker seems to generate a long SQL query with numerous joins when I try to achieve the same outcome.

Here's my setup:

I have an explore defined with relationships between tables using the join function in LookML.
When I attempt to visualize a single field in a Looker exploration, the generated SQL involves joining multiples related tables.
My Question:

What's the best approach to display only one dimension in Looker explores without unnecessary joins, especially when dealing with complex relationships between tables?

I'd like to discuss how you were able to get the job done for your client. Would that be possible?
Best regards

Hello, 

I am in the situation where i need to migrate universe to looker model. 

is it possible to have a demo on how you transform a universe to looker model ?

maybe if you have a blog where you describe it ? or here ?

Thank you so much

Hi Otaku, 

I don't usually go on this forum. Sorry for the delay in my response.  Find here a short description about the way we do that. Kr, théo
