Universe and SQL table

[Former Member]

Hello Experts ...

I have a point isn't clear i would like to ask about please. In Universe Designer when i import tables from SAP ECC SQL database or SQL Database not an SAP source if this tables are joined in SQL, does this joining schema imported also when i insert those tables in the universe designer.

Again i repeat in simpler way, in SQL i joined the field table1.name with table2.name and saved that as a database when i import this database in Universe Designer and import those 2 tables again table1 and table2 i will find the field i joind in SQL also Joined in universe designer or the joining schema doesn't included in importing ???

i hope you could understand my question and point of view. And thanks alot for your time.

Best Wishes ...

Please note that accessing tables directly in the underlying SQL database of an SAP ERP system is not recommended. Some of the SAP data is stored encoded in the tables and therefore you may not have access to all data available in SAP ERP.

Thanks a lot for help experts. I think i understood now that point in brief if i import view from SQL it's already joined relational database and if i import tables it's standalone database no joins defined and then the webi depend on the universe join schema and work on the universe structure not SQL.

I think that may cover my questions in this thread. thanks again for help

Thanks a lot for your help that was really helpful but i have another questions please concerning the same idea. the joins schema made by universe when i select automatic detect it joins the tables depending on it's name which mean there could be join in different manner in SQL but universe joins in another way. For example i have table1 (id,name,dep) , table2 (dep,dep_name) so i joined the table1.id with table2.dep in SQL, while in universe it gives the automatic join to table1.dep with table2.dep ....

another question if i assume that this join is correct so why or how i can join again on universe designer. for example table1.id joined with table2.dep in SQL how could i change this in universe to be table1.dep with table2.dep is this applicable to be 2 different joins on same field ???

Hey Marwan Ellaboudy ,

how i can join again on universe designer

>> Double click on Join and point to exact field. It should work. Do Parse also.

for example table1.id joined with table2.dep in SQL

how could i change this in universe to be table1.dep with table2.dep is this applicable to be 2 different joins on same field ???

>> Yep, you can have 2 different joins on different fields.

Now your join looks like this:

table2.dep between table1.id and table1.dep

Hope it gives some idea.

Gracias...!!

BOCP - BOE ... ,

Thanks a lot for your help one of your answers on my question i need to clarify it more when i asked about the join in the universe " how could i join in the universe " i was wondering about how i could join an already joined field from SQL, as i said it's already joined in SQL table1.id with table2.dep how could i rejoin or change the join schema in universe to be table1.dep with table2.dep ?? i was wondering is this right to make so i know how to do so but is this right to make that "rejoin in universe" and why could i make that is there certain cases need that ??. i hope that my question is clear, thanks a lot again for your help.

Hey Marwan Ellaboudy,

In that case I suggest you:

Create Alias tabless for table1 and table2 and join as you req @ universe.

table1.dep = table2.dep

Hope you got my point.

If you have already maintained any relationships at back-end level(DB) then when importing them to Universe to get that relation up:

Go to Universe Designer:

In Properties:

Strategy Tab:

Join : <place> Make Automatically joined from DB (am not sure about the text)

after doing this you can see them, no need to do manually.By default, it set to (manually ,,,,,,,,,,,)

Hope I understood your req.

Oops...!! Not seen prev post.

Gracies...!!

depending on designer settings (specially in strategy ) while creating universe, joins are created. if the strtategy is set to automatically detect the joins based on the column names, it does bring the joins. if it is set to manually assign joins, you have to join them.

it is always suggested to join them manually.
