Okay, I'm going to try and explain this and hopefully it makes sense.
I have begun creation of a workapp to integrate all the various tools we need as a company to onboard employees and I've run into a wall with one aspect.
First of all, i am creating this so that all the dozens and dozens of hiring managers in the company at site level do not need to be taught how to use complicated computing systems like excel and smart sheet. I want them to fill forms and the rest is automated. So the first sheet I am creating is the employee metadata sheet which will contain all their information from name to emergency contacts to uniform size etc. This was easy and the corresponding form simple as pie. So now a manager can input a new employees data by filling the form without ever touching something they might not be familiar with such as a smartsheet. Great.
My problem is when that metadata needs to be updated. I don't want the managers going into that sheet as it will contain personal information from people all over the country they have nothing to do with, once completely set up, potentially up to 9000 people will be active on that sheet at any given time. So I want a way for the manager to open a form of some sort, and be able to easily find that employee so that they can update that particulars employees metadata without every seeing the smartsheet. The problem with a dropdown is you have to populate it first and at any given time dozens of employees will become active or inactive in a day, no one has time to continuously manually populate a dropdown, so the information that would be on a drop down if that is the solution would need to self populate.
My company works with the entire microsoft 365 suite so any integrations this would need is it does in fact need it (not integrating and using host sheets or whatever would be better) would be best using a microsoft app of some sort.
