I have a requirement for a custom field on Account that will have a drop-down with values that are dependent on the user. This was already "implemented" prior to me getting here and it wasn't done in a way that I would ever do. The current implementation has three custom option set fields, one that everyone sees and 2 that are user specific. Processes were created to hide the general field and other user specific field and only show the field specific to the user. This solution has problems and I want to scrap it considering I now need to add 1 more specific user and a group of 6 users that all need the same dropdown options. Ideally I would like to create a single field on Account where the drop-down is dependent on a role or some other field on the user and not specific users. I am new to Dynamics with some Salesforce experience and many years working with Siebel. I found some different ways of implementing drop-downs dependent on other drop-downs using code or lookups. I'm really just looking for the best approach not a step by step how to implement it.
1. What would be the best option on the user record? Role, custom field?
2. What is the best approach to dynamically filter the options on the Account custom field based on the user's role/custom field?
