Hi Prasad,

The rules in all these 3 systems will be different. There is a different rule set for CRM. There is no ruleset for BW. So it is recommended that we use atleast basis rule set. For ECC you use the R/3 rule set. For CRM the crm ruleset + Basis ruleset.

Thanks,

Prasad,

To build on Chinmaya's explanation, make sure you use a logical system for CRM, BI, and ECC for the basis portion of the rule set (and only the basis portion). This will keep you from duplicating your rules to meet your basis requirements. The other rules should be attributed to the individual systems (or additional logical systems if including mult landscapes, ex. Dev, QA, and Prod ECC merged into one ECC logical system).
