So, I have a list of projects, with a bunch of bidders bidding on and winning those projects. My sharepoint site is a communication portal with a list that contains project information, statuses and etc.
The site is initially set up to share information internally and the access to this particular list is blocked. However, I am wanting bidders to have the ability to access this list in the future to update the list with the latest information (status, timeline updates, project documentation, etc) if they have won the project. However, I do not want the bidders to be able to view in any way the other projects they have not won, for very obvious reasons.
I understand this can be easily done with a filter, but I am uncertain how I can restrict access of other contents for a project they have not won. Any suggestions on how I can implement this other than changing unique permissions of all the projects on the list?
I have reviewed some other solutions, but it does not seem to provide a viable solution.
