Granting Read access to Category for specific Groups using PowerShell Scripts

Question

For reference please see the script running for updating the category with specific groups and granting read permission:-

$groupI  = (Get-TridionGroup -GroupName "Group I").Id
$groupIRead = @{}
$groupIRead.Add($groupI, "Read")
Update-TridionCategory -WebdavUrl "webdav/C010 Dummy Schemas/Dummy" -Permissions $groupIRead -Verbose 


$groupII = (Get-TridionGroup -GroupName "Group II").Id
$groupIIRead = @{}
$groupIIRead.Add($groupII, "Read")
Update-TridionCategory -WebdavUrl "webdav/C010 Dummy Schemas/Dummy" -Permissions  $groupIIRead -Verbose 

After running the above script category is updating with only GroupII whichever group is executed at the last only with that group category is getting updated.

I think you're overwriting your permissions. use one update statement. add both groups to your hashtable. not tested, but I think this will work:

$groupI  = (Get-TridionGroup -GroupName "Group I").Id
$groupRead = @{}
$groupRead.Add($groupI, "Read")

$groupII = (Get-TridionGroup -GroupName "Group II").Id
$groupRead.Add($groupII, "Read")
Update-TridionCategory -WebdavUrl "webdav/C010 Dummy Schemas/Dummy" -Permissions  $groupRead -Verbose
