We are currently using SUS.
After business partner is transfered from EBP to SUS via XI, an email is generated to the vendor with a registration ID that allows him/her to use SRMSUS_SELFREG to register an admin user for that company.
When the user registers based on the auto-generated registration ID, the screen outputs "Business Partner Does Not Exist".
I am very stuck at this stage and can't find more places for an error log or any leads.
Please help.
