Assign Task in Salesforce1
|Knowledge Article Number||000229156|
|Description||Why am I seeing the message "Looks like there is a problem You do not have the level of access necessary to perform the operation required. Please contact the owner of the record or your administrator if access is necessary." when I am trying to assign a task to another person
Below is a screen shot of the message you would be seeing on a tablet
|Resolution||When you are working as a standard user and trying to assign a task to another user, you would be seeing the warning message because, all tasks are private in salesforce by default. Once you assign your task to the other person the task record becomes private for the other user and you no longer has access to that task.
If you are a system admin of the company you would not be seeing this warning message as you have full access to every record in the org.
Please keep in mind that the message you are seeing is just a warning and the task is getting assigned to the other user or the action is getting performed.
