Sankar,
You have mentioned:
- Vendor is extended to P.Org V (L.Sys - 100) in SRM but not in VENMAP table -> Where id you check this (portal/bbp* transactions)
- Also you have mentioned Vendor is not in LFA1 table (L.Sys - 100), if vendor is not in ECC how do you expect it to be replicated to SRM -> So, please check (if relevant) in the L.Sys - 200 if the vendor is present in the LFM1 table.
Relevant tables:
Table BBP_VDSYNC_CUST - LATEST SYNC report
Table BBPNEWVD_LOG - shows which vendor from the back-end newly added.

You can verify in portal to check the P.Org to which a vendor is extended to.
Also, check if this happened for only supplier ?
