Title
Error while expanding the changes in the generated report when comparing two backups -
Description
While generating comparison reports between backups. When the report contains a smaller number of differences (e.g., around 100), it is generated successfully. However, when the report includes a larger number of differences, it fails to generate and displays an error.
Additionally, when comparing the two backups for changes, the report correctly identifies and generates the object details that have changed. However, when the user clicks "Expand All" to export all the details, it throws the following error:
"A data source instance has not been supplied for the data source 'Report Header'"
-
Cause
The issue appears to be occurring somewhere inside Microsoft Report Viewer.
-
Resolution
We have created a bug item for this issue to be corrected in future release.
