Delta initialization without stopping posting of data

21 Views

Hi,

Some thoughts and questions about subject...

My question is in which situations can delta enabled extraction be initialized (safely) without stopping posting of data? Put more generally - Which types of delta supports not blocking posting of data during initialization, and how do I tell in the BW/R3 system if a datasource has this property?

Another question on this topic is: If a datasource normally would require stopping posting of data during initialization - is there a safe way to avoid this scenario - e.g by using initialize without data transfer and then do a full load to catch up with historical data? Would that work without stopping posting of data?

My own toughts:

I know that the postings don't have to be stopped if the extractor supports Early delta initialization. But in which other cases, if any, can it be done? I would guess that postings doesn't have to be blocked for some types of delta extractors - e.g if the extractor uses generic delta based on timestamps and doesn't use delta queue...

Sorry if I post about a topic already discussed in these forums, but I didn't get any full answer from previous posts (though I might have missed it).

Many thanks! This would be really valuable information for me!

Best regards,

David
