Field dependency between Two fields in Incident form

[chaithanya gund]

Hi Team,

I have two fields in Incident Form 1. Sub Category (Which is Choice List ) and Service Offering field ( which is a Reference field to Service_offering table where 44 choices are present). 

My Requirement is when a Particular Sub category is selected for Ex: Hardware then only Service Offerings related to Hardware should be visible in the Lookup of Service Offering (Ex: 4 Service Offering are related to Hardware) and remaining 40 Choices in table shouldn't be Visible. And in the same way Sub category is selected for Ex: Software then only Service Offerings related to Software should only be visible in the Lookup of Service Offering and other choices should be hidden.

How can i Achieve this requirement. Request you to provide your Suggestions.

Thank You!

Hi @chaithanya gund ,

Just to pitch - then why? There is a best practice OOTB in relation to business service and service offering according to CSDM. Why have a dependency towards hardware? I would recommend you to challange the requirement instead of doing this, as I could foresee a rather huge overhead of maintaining this.
