Master data in a global environment is controlled by one source to ensure the single version of truth. BI and ERP system has to share the same type of master data as it is only appropriate that the master data comes from the r/3 system and BI extract from there. In some cases where the master data is not in r/3 system, the BI extract it from the global master data database.
Scenario 1
In BI reporting, the version of master data reported depend on the period selection. If material group in year 2009 month 12 is reported as Semi Finish Good and in year 2010 month 1 is reported as Finish Good, how does BI actually cater for this scenario?
Scenario 2
If the material classification in R/3 takes from GS_XXX and now it's replaced by GS_YYY, how does BI changed according to the material attributes extraction?
In scenario across BI landscapes eg in different regions and one global BI instance in which all the regional master data flows up to global level, the master data has to be compounded with source system as the object might have the same name, eg. same material code may exist in two different regions, an error stack may have te same technical name in two or more BI instances.
