Hi,
Assuming as you have done all required settings to replicate your data source to bw.
While replicating data source into bw, which version you replicated.
in 3.x or 7.x(RSDS).
If your data source was active in bw server, please check the table SE11- RSDS, enter your data source and check it. if not available then your data source in 3.x version. need to migrate to 7.x.
Thanjs
