New source system and 0logsys

[Former Member]

hello,

We already have a BW production system connected to a unique SAP R/3 system.

Our infoproviders (ODS and infocubes) and our infoobjets are not compounded with 0logsys or 0sourcesystem.

We have to connect a second R/3 system to our BW systems.

Our problem is that we will be able to find master data with the same range in each system (for instance costcenter XXX will exist in both system but with different attributes).

My question is :

do I have other solution than adding 0logsys (or 0sourcesystem ?)as a compound of each master data we use and in all providers ?

Can you confirm me that for adding this compound "everywhere" i will have to empty all my infocubes/ods/master data ?

I've never done such transformation in BW so If you have advice to give it will be nice.

Hope my question is clear...

Thanks a lot

Hi Lea,

If you to want the 0legsys value along with historical data then you need to delete all historical data.

In case if you want the 0legsys value information from presnt data loading onwards then the following links will be help you lot...

Thanks for your answer.

Vikash : I don't really understand your point 4. What do you mean by "pass on the old logsys value (manually)"

PRK : the links are usefull but deal only with ODS/Infocube.

Do you know if there is a way not to delete master data records to add a compound in the infoobject ?

Hi,

My advice will be -

1. Find out the Master data which will have common values in both the systems

2. freeze the list

3. compound source system to only these Infoobjects

4. in existing data - I think (need to explore) you can pass on the old 0logsys value (manually), before connecting to another R/3 source system

5.start taking the data from new & old after connecting & compounding.

try this first on Dev system.

hope it helps
