KB14045: Error ‘A derived metric’s leaf used in this report was not selected during prompting or is not available’ occurs when executing a Report Services document in MicroStrategy Developer

SYMPTOM:
When a user executes a Report Services document in Strategy Desktop 8.x, the following error occurs:

Error Message below:
"Report processing could not be completed. An derived metric's leaf used in this report was not selected during prompting or is not available. Please edit or re-run this report so that all of the required metrica are available** Error Code=-2147212244"
 
CAUSE:
 
This issue occurs when a metric, that is used as part of a derived metric, is removed from the report that is part of the data set.
ACTION:
If the user knows which metric was removed from the report, follow the steps below:

1. Return the deleted metrics to the original report.
2. Save the report.
3. Remove the data set from the Report Services document and add it again.
4. Execute the Report Services document.

If the user cannot determine which metric is missing or was removed from the parent report, creating the document again will prevent the reference from being lost.
