Why do I receive a "Unable to Access Page" error when I edit a field
|Knowledge Article Number||000199539|
|Description||On occasion, System Administrators may receive the following error when modifying field values on an object that has Roll-Up Summary fields.
Unable to Access Page
The value of a parameter contains a character that is not allowed or the value exceeds the maximum allowed length. Remove the character from the parameter value or reduce the value length and resubmit. If the error still persists, report it to our Customer Support team. Provide the URL of the page you were requesting as well as any other related information.
|Resolution||The source of this issue is one or more of the Roll-Up Summary fields is currently recalculating. Roll-Up Summary fields lock the object from changes while it is recalculating to avoid any changes to the recalculation due to a change in the fields. To resolve this issue, wait until the recalculating field has completed the recalculation and then make the field change.|
