Symptom and confirmed scope
Elastic Report 5.0.5.1 generates an HTML report without the requested minimum and maximum results. The reported installation runs Rapid SCADA on Raspberry Pi, and the report completes without an error message. The same omission occurs with the default Elastic Report configuration, so the symptom is not isolated to the custom channel definition.
| Evidence item | Observed state | Diagnostic meaning |
|---|---|---|
| Elastic Report version | 5.0.5.1 | Defines the affected version reported in this case |
| Platform | Raspberry Pi | Must be included when selecting and validating an update |
| Report output | HTML view | MIN and MAX are absent from the generated result |
| Errors | None reported | Troubleshoot output behavior rather than an explicit runtime fault |
| Default configuration | MIN and MAX also absent | Reduces the likelihood that only the custom XML causes the problem |
Check the aggregation request
The custom section binds column CH001 to channel 403, requests the channel value with calcType="Val", and enables both aggregations with calcMin="true" and calcMax="true". It uses a TimeData section with daily time detailing.
<Column name="CH001"
cnlNum="403"
calcType="Val"
colStyle="col-xs"
calcMin="true"
calcMax="true"/>The evidence does not establish whether HTML view supports every formula type, nor does it identify an additional display option for MIN or MAX. Do not add an undocumented attribute. First confirm that the deployed XML retains these attributes and that the generated report still omits both results.
Isolate configuration from the installed build
- Generate the custom report and confirm that both MIN and MAX are missing while the main value output is present.
- Generate the supplied default Elastic Report example for the same working period.
- If the default example also lacks MIN and MAX, record Elastic Report version 5.0.5.1, the Raspberry Pi platform, and the absence of errors. This reproduces the reported build-level symptom without attributing it solely to channel 403 or the custom section.
- If the default example displays MIN and MAX, compare its section, column binding, and calculation attributes with the custom XML before changing the installation.
Apply and verify the available update
The supported resolution path in the evidence is to try the update supplied for this issue. No update version, package identifier, installation command, or confirmed outcome is provided, so obtain the applicable Raspberry Pi update through an official Rapid SCADA distribution or support channel rather than assuming a package name.
After updating, rerun both the default example and the custom daily report. Accept the result only if MIN and MAX appear in the generated HTML output and report generation still completes without errors. If the values remain absent, provide the XML, Elastic Report version, platform, report output, and error status to official support.
FAQ
Why are MIN and MAX missing from Elastic Report 5.0.5.1?
The reported 5.0.5.1 installation omitted MIN and MAX without producing errors, including when the default configuration was used. This points away from a fault limited to the custom channel definition, but the evidence does not establish the internal root cause.
Which Elastic Report XML attributes request minimum and maximum values?
Set calcMin="true" and calcMax="true" on the report column. In the reported configuration, those attributes are applied to channel 403 with calcType="Val".
How do I verify an Elastic Report update fixed missing MIN and MAX?
Regenerate the default example and the custom HTML report after applying the applicable update. Verify that both MIN and MAX appear and that report generation completes without errors.
