Vendor not intended for purchasing org

Hi Gurus,

System details :

SRM 5.0

ECC 6.0

ECS -- Extended classic scenario

Org structure :

Root node -- > FI dept

Porg > pgroup > SC users

Vendor groups:

Root node

Services

Vendor replication :

Tcode : BBPGETVD

SYSTEM : Backend system

Vendor no : XXX

Pur org : PUR1

OBJECT ID : Org unit of vendor group

and replication was proper..

When i check the following tables : BBPM_BUT_FRG0061, BUT000 and VENMAP Tables I could see the relation between them,,

But unable to figure it out where is the problem...

Please mention step wise so that we can close the issue..

Points will be rewarded
