Mass upload of vendor data in SRM during implementation

Hi Experts,

We are under implementation of SRM 7.02. Through our implementation partner we have developed two vendor registration forms (Form-I and Form-II) which contains several fields which is fully customized as per our requirement.

Business Requirement:

For the existing vendors we want to collect the data off line through conventional methods and then want to do the mass upload in the back end in Form-I and Form-II as per the field requirement of Form-I and Form-II and on the basis of the same and after that

1. Existing Vendors shall be uploaded (mass upload) in SRM with all required information as per the requirement

2. BP numbers shall be generated and automatically linked to ECC Vendor numbers User ID and corresponding password will be automatically generated by the system and sent to respective vendors through email
