Hi Roel,
Can you follow the below steps.
1.Ensure the Configuration for Tasks/profile types assignment for BW is correct.
2.Activate all the applicable datasources such as 0RT_PA_TRAN_CONTROL, 0RT_PA_TRAN_LOYALTY
3.Check the QRFC outbound queue and try to process the LUW entries, if they are not yet processed.
Hope it helps
Best Regards,
Aram.
