Hi Hari,
BDLS run is supposed to be done by Basis team, please reach out to them.
one check from your end what you can do is, check table RSTRAN for some transformations(TRFN)...
TRFN name should include the corresponding source system name which is connected to Quality system.
If you see that TRFN has source system name as that of which is connected to BI Prod then its a issue. Basis has to correct this,
Regards,
Gaurav
