I am trying to develop the ETL for CRM-BI process, I had two questions before I got started,
1) How does data from CRM get tranfered from CRM to BI. I know data from R/3 to BI gets transferred through IDOC's, does the same happen from CRM to BI too.
2) How do delta's work in CRM. For example in R/3 ( Logistics) we have Direct, Queued or V3 update, do we have the same options in CRM too? I specifically need to know how it works in opportunities, activities & account planning areas.
