Hi Dubravko
really good to see you that active here on SCN lately!
SAP Netweaver does not implement foreign keys on DB level. So all tables are independent from each other for the database and one can insert, change or delete records without having to drop or disable any constraints.
SLT in turn handles all tables separately - which actually does lead to a situation where data that was written together in a single transaction on the source system is now written in multiple separate transactions on the target system.
As the full data of any transaction will eventually get transferred, the data will be consistent after some (presumably short) time.
