Purchaser Accepts Vendor - Related workflow is not being triggered

Hi,

All

We have an SRM7.0 system and a separate SUS client for vendor registration. Once vendors have filled in the registration form,

the Purchaser must be able to view them and accept them into the SRM Internal directory.

Whenever Purchaser tries to accept a vendor (in the portal) standard wrkflw 14000030 shud be triggered etc etc.

Thus Purchaser's manager must be able to accept the supplier.

Problem here is: -

Once the Purchaser accepts the vendor, Workflow WS 1400030 has to be triggered but the workflow is not being triggered and this is a standard one.

Can any one please help me in this regards, and tell me with the feasible solution for this.

Thanks in advance,
