Hello everyone.
Today I will talk about a specific configuration of the permissions
Problematic
As an administrator of my site,
I want my members to be able to add files / items but not to be able to delete them
In order to avoid unwanted deletion of information.
Reason
The standard permission level for members is “Edit”. This level of permission is sometimes replaced by the lower level “Contribute”. These rights allow members to participate in the addition of information to the site but also by default to delete the content.
Resolution
To resolve this issue, we will create a new permission level that we will call “Contribute – No Delete”. We will apply it to the member group at the site level.
Go in the site settings
Under “Users and Permissions”, click on “Site Permissions”
On the ribbon, click on the “Permission Levels” links
Choose the permission level “Contribute”
Scroll down and click on the “Copy Permission Level” button
Add the name “Contribute – No Delete”, set a description and untick the “Delete Items” and “Delete Versions” permissions
Scroll down and click on “Create”
The permission level is created, go back to the “Site Permission” by clicking the “Permissions” link
Select the “Members” group and click on “Edit User Permissions”
Select only the “Contribute – No Delete” permission level and click on ok
Now your members will see this in the ribbon when they select an item
“Edit item” is accessible but “Delete Item” is greyed out.
Hoping it helps.
Christopher.
