Hi Milind,
Its LO std datasource, I hope you are working in Dev system.
If this PVZNR field is not available in BI, then its not part of transfer structure.
So go to RSA6 (Post processing of datasources) then go to change mode unhide the required field and save.
After checking at RSA3, replicate the datasource at BI side by using Tcode RSDS.
Activate the replicated datasource in BI side.
Find the relevant field in target and do mapping in transformation.
Trigger the infopackage and check.
Thanks,
Somesh.
