CNs are being deleted accidently because individuals are using the Actions button (on the CN) instead of right-clicking and choosing Delete.
We've had multiple cases where a CN was nearly finished for submittal, but had 2 Change Tasks in the Implementation Plan, one blank and one containing the required information. In an effort to remove the blank Change Task, the undesired change task was checked/selected using the checkbox, then the individual moused to the Action button. From that pulldown, "Delete" was selected to presumably remove the checked/selected incorrect change task item.
Instead, this action deleted the entire CN, without any warning, and the document was not recoverable.
— How it appears you should delete an Implementation Plan's Change Task: Select the Change Task >> Select Action up at the top (with Change Task selected), >> Then from the Action menu select "Delete." The warning is not clear that you are deleting the whole change object.
— What is supposed to be done: Select the Change Task >> Right Click >> Select "Delete"
ISSUE: Depending on where the CN is in the workflow, the CN is deleted but the objects are in the middle of being processed. This causes a problem, not only did you lose all the CN data and signatures but now you have to try and recreate it and address the issue of the Resulting Objects being at the wrong state.
1) Add an Action button on the Implementation Plan table
2) Give a warning as to what you are deleting. Such as "Are you certain you want to delete CN###### object." (Basically, have the system tell you what you are deleting.)
Be consistent throughout Windchill. Sometimes you use the pull-down for options, sometimes you use right-click.
