create relationship between assigned group and business service

[Jorge Huarcaya]

I need to create a dependency between the business service and assigned group fields, this in order that only certain groups can be assigned to certain incidents with a certain business service, for example. Business service 1> group 1, group 2 business service 2> group 1, group 3 when the incident has business service 1, only groups 1, 2 and not 3 could be assigned if the incident has business service 2, only group 1.3 could be assigned and not 2. can you please help me how to do it? Greetings.
