In the service catalog form there will be three fields
1. Domain-multiple choice
2.application name-reference variable (cmdb_ci_business_app)
3.security group name-single line text
By using this one hear I have a one requirement if user selects domain the domain value is populated as a prefix in the security group name
If the user select application name then it takes application number in the backend table and post populate after the domain prefix
Example security group name = domain_applicatioNumber
