Delay in data transfer from ECC to BW with 0CA_TS_IS_2
The reason for that is a built-in delay which is set to 2 hours as default. In the delivered standard, it can be changed in BADI CATS_CUST_ISOURCE if needed.
The data source 0CA_TS_IS_2 is designed to be used together with 0CA_TS_IS_1 which reads the approved records. In Delta Update mode 0CA_TS_IS_1 is writing a time stamp that is used by 0CA_TS_IS_2 as upper limit. If 0CA_TS_IS_1 did not yet run, the limit is initial and 0CA_TS_IS_2 cannot extract any records.
