After update of BW4/HANA: very low extraction performance on non SAP source systems

[former_member637950]

Hi experts

We updated to basis version SAPK-75308INSAPBASIS, DW Core SAPK-20011INDW4CORE.

All data from SAP source systems are extracted in a normal expected time. Only non SAP source systems, here ORACLE DB, are extremly slow extracting the data. By a factor of 50 more time is needed. These systems are connected via HANA Smart Data Access. The data volumne on the source side has not increased.

I didn't find any SAP notes. Does anyone had the some experience?

Thanks!
