Thank you for being patient.
I have come up with a solution to implement what you are trying to achieve after doing some research and trying it out. Here's how it works:
As shown below, create a table “TableGroup_Users” for mapping Groups and Users. You can control which users are allowed access by using the following table:
Create a new table, "TableAccess", that contains options and group mappings as well as a column for "OptionsDescription".
The TableAccess table has another important column, "user_RLTableGroup", which is a rowlink to TableGroup_Users. Rowlink has been calculated using Group value as below:
ON THE SCREEN:
I have created a list and set the source to:
=FILTER(TableAccess,"$[SYS_USER] IN TableAccess[user_RLTableGroup][ColumnUsers]")
The formula above displays the options that pertain solely to [SYS_USER].
This is how the app will appear, its displaying the options which belongs logged in user:
I hope this is helpful. If you have any further questions, please feel free to contact us.
