Sigma FAQs

Can the configuration to change the font size be turned off?

Not enabled as of now. It is always turned ON.

Does reports have RTL support?

Yes.

Can Charts be included in the report?

Yes. The App Designer feature in the Studio can be used to create the chart as a individual app (widget). The Template Designer in Report configuration can be used to map the chart to the report. The generated report displays the chart and the report data.

How to view a report generated a month back?

It is currently on road map. A filter shall be enabled to generate older reports.

Can the template used to render the report be modified?

HTML editor is provided in the design area to modify your reports.

In the data builder what is the difference between record and object?

Record is a combined selection of rows in the table.

Object is an individual selection of an item in the table.

What is a derived column?

A dummy column which can be used for computation purpose to deduce a value and use in report. Refer Displaying Collated Headers in reports for more information.

Can data entitlements be controlled? eg : Generate the reports for a specific set of clients

Yes, based on system filter and default filter.

What is the maximum number of columns that can be configured in the report?

You can add columns without limits, however column length should be specified appropriately to avoid error scenarios.

For example, if your specify 10 characters for an address column, the entry should not exceed it.

When the report / data source configuration changes is it enough to run the generated report again or should a child report be created?

When the data is updated, it gets reflected when you run the report. However, the structure of the database should not be changed.

In cases where data is aggregated and there are no child records, instead of printing an empty page with no data message, enable a configuration to avoid adding it in the report

Currently not supported.

End of report message should be a configurable option in cases where data aggregation is used.

Currently the End of Report option is enabled for all. You can however modify the End of report message.

How to combine multiple reports into single file?

WTRN0006W: Transaction {0} has timed out after {1} seconds

For example:
```
WTRN0006W: Transaction 00000188D7CBD648000000455D953708CCA97D4013E3EDB45FD179E3597A7D478393378300000188D7CBD648000000455D953708CCA97D4013E3EDB45FD179E3597A7D478393378300000001 has timed out after 120 seconds
```
Solution: Increase the total transaction lifetime timeout and maximum translation timeout in seconds. These settings can be updated through the WebSphere Application Server console, using Servers > Server Types > WebSphere application servers > server_name > [Container Settings] Container Services > Transaction Service

Run the following commands as user SYS:
```
grant select on pending_trans$ to <user>;
grant select on dba_2pc_pending to <user>;
grant select on dba_pending_transactions to <user>;
grant execute on dbms_system to <user>;  //If using Oracle 10.2.0.3 or lower JDBC driver

Instead of updating the CanvasApplicationContext.json file, update web.xml in the 19.1.7.11 19679 revision and above.

If the latest release revision is 19.1.7.11 19679 and above, refer to the following steps:

Perform the following steps to use the CT release as-is without the need to update the CanvasApplicationContext.json file in the CTResources.jar.

Update web.xml in Canvas Studio WAR

File Location: ...\webapps\ctmodelhouse\WEB-INF\web.xml

The following snippet provides the sample values of the necessary elements and attributes that are to be configured within web.xml.

<context-param>
<param-name>appId</param-name>
<param-value>MODELHOUSE</param-value>
</context-param>

The param name should remain unchanged. Only "appId" should be used.

If the context-param attribute is already present in the web.xml for a different param-name, the new context-param attribute has to be added after that to configure the value of appId.

Refer to the following snippet for sample values of the necessary elements and attributes that are to be configured within web.xml.

<context-param>
<param-name>ModelHouseInitializeBundle</param-name>
<param-value>MyImplementation</param-value>
</context-param>
<context-param>
<param-name>appId</param-name>
<param-value>MODELHOUSE</param-value>
</context-param>
