Steps following a user creation request :
If the user does not provide his PC Solvay ID in his request, it can be displayed in BMC Helix by searching the user and checking the field : Connection ID

If this information is not available it must be spoted by asking the user directly.
If the user creation request is related to a replacement, the SCOPE is identical to the replacement. The key information to spot is : Who is going to be replaced ? His user ID can be deactivated ? and When ?
