Users may run into an issue where certain fields are marked as read-only on the variable editor portion of a Requested Item (RITM), even though those variables have write roles assigned that should allow them to modify the fields.
Release or Environment
This can be caused by containers that have different roles assigned. For example, if a variable with a write role of "ITIL" is within a container with a write role of "nobody," then the variable will be read-only on the RITM to a user with the ITIL role.
If they are present, remove the write roles on the container variables within the Catalog Item that spawned the RITM record. It is not recommended to use write roles on containers in general.
