Hello everyone. I have 2 issues that I need your help with: 1. My Glide app currently has 2 sales employees using it. However, when both individuals use the app simultaneously to calculate product costs, conflicts arise, where one person’s actions overwrite the other’s before any results are obtained. How can this situation be addressed? 2. Can multiple users be granted different permissions within my Glide app? For example, can some users input data while others can only view the data without being able to make any changes, even within each tab? Tks all ---

Depending on the app here are the key concepts for each issue: 1. User Specific Columns This feature allows your app to store data for a specific user within a shared table. Probably the feature you need in this example. From the Glide intro: “User-specific columns allow cells to hold unique data for each user. This means each user can experience their own data for a particular part of your app.” > **[User-specific columns | Glide Docs](https://www.glideapps.com/docs/essentials/security-and-user-data/user-specific-columns)** > > Allow cells to hold unique data for each user. 1. Row owners Manages access to the underlying rows based on a User’s ‘role’/permission From Glide’s into: " If your app has data that some, but not all, users should access, then you should use **Row Owners** to protect that data." > **[Row Owners | Glide Docs](https://www.glideapps.com/docs/essentials/security-and-user-data/row-owners)** > > A secure way to restrict access to certain rows.

Could you guide me in detail on how to create special columns for each user to address this issue? Tks you ---

wow i miss this interface !! you need to use user specific columns for example for Number of people. when you create the column in the data editor… (tick the user specific checkbox). it means the value is only for that user. ---

I’m clueless about this. Could you provide more details? Maybe even screenshots of the editing interface in Data. Thank you. ---

Could you advise me on a template app on Glide that utilizes User Specific Columns and Row Owners so I can learn? ---

Here is a tutorial on the topic: > [@thinking Row Owners vs. User Specific Columns](https://community.glideapps.com/t/row-owners-vs-user-specific-columns/58205): > > Row Owners and User Specific Columns in Glide both provide a way to secure, privatize, and personalize user data, but which one should you use in your no code app? Join me as I walk you through a few different scenarios as to when you’d use each (and when you WOULDN’T use either!).
