Question Expression editor field in non editable

I am not able to update the sql operation.The expression editor panel is non editable.How can i make it editable?

Hi,
Maybe this SQL Operation cannot be edited because it belongs to another process (or template) which was included in your main process (or mapping).
In this case, you can edit the original process, or right click in the process breadcrumb to enable "Edit".
If this SQL Operation belongs to an official template, please test your modification and submit it to the Support team for approval.

Please provide more details if the above information does not help.

Im able to edit after right-clicking on the process bread crumb and enabling edition.Thanks a lot Thomas.
