Does anyone know of a document that summarizes the different ways of getting data out of SAP (bulk/batch rather than real-time although having that documented also would be handy) ?
The ways I know of are:
Data Services (obviously)
OpenHub
SLT replication (I think - don’t know much about this)
ERP - ABAP reports ?
If nothing is documented, is there anyone more knowledgeable than I would could come up with a quick summary ?
Guess you covered most of the batch options. Adding some more detail from what I know:
SLT for HANA - I believe this is primarily to replicate SAP data into HANA, and cannot be used just for any other DB/target. It comes packaged along with the Hana license. Definitely the way to go for real time operational reporting on HANA if SAP on HANA is not an option.
SAP DS - Via SAP tables(RFC read)/extractors/BAPIs. Also directly from SAP backend tables via SQL. (BASIS folks may not be to eager to share backend access)
SAP BW - BW data can be extracted via Open hub/ RFC Table read. Or by directly reading the backend tables via SQL.
