BW: About initialization, about the Delta Mechanism

Over the past few days, I have made some experiences in initializing 18 data sources ~ Summary

First, lbwq or smq1, Which is outbound queue and must be deleted. If the extraction structure is not modified, the LIS extraction job will certainly report an error.

Because the new business data will be saved to the outbound queue first, and then extracted to the Delta queue, with a cycle of 1 h (which can be planned in lbwe)

Secondly, why do we say that the LIS data source is push, and the FI and self-built data sources are pull? I have a bit of understanding.

The so-called push means that the business data will run into the Delta queue by yourself, waiting for you to smoke.

The so-called pull means that the data will temporarily capture the relevant data from the R3 system table when you run the D package based on a field such as time stamp or date.
