How to use internal classes in "my model"?

Posted on by DAX Dev

Hello,

I would like to run the electronic report from my form.

For that I have created a class and tried to use ERFormatMappingRun class, which is used to run electronic reports.

Compilation gives below error:

Class 'ERFormatMappingRun' is internal and is not accessible from the current module 'MyModel'

I understand, that it can be only used within it's own model, but what are the workaround to use internal classes' logic from my model?

Thanks.

Internal classes can used only in the package where they are defined.

There is no workaround to use them.

But, there can be ways to solve your business requirement, which don't require you to call those classes from your code.

Could you share your business requirement?

We have created an electronic report for transfer orders, which generates the excel file.

The requirement is to have a menu item on Transfer orders which will execute that electronic report.

We have a parameter which points to the ER configuration.

You can't use the internal class ERFormatMappingRun, but you can use the public interface ERIFormatMappingRun. Use ERObjectFactory::createFormatMappingRunByFormatMappingId(), for example, to create an instance of the interface.

You'll find a plenty of examples in the standard application. This one is from EuSalesListReportingEngine.generateFile():

ERObjectsFactory::createFormatMappingRunByFormatMappingId(formatMappingId, _filename) .withFileDestination(fileDestination) .withParameter(new ERModelDefinitionDatabaseContext() .addQuery(tablenum(EUSalesListReportingGroup), salesListERQuery)).run();

Hello Martin,

I was able to generate the file using similar approach. As I understand by testing, we need to have Electronic reporting destination --> Destination settings --> File enabled, in order the file to be automatically downloaded. So, I have set it enabled and file is generated and downloaded.

We want to apply little bit different logic during "Ship transfer order" process.

During this process file must be sent toa predefined E-mail address.

Wat would be a best approach? Should I create another file destination setting for e-mail? If I enable both "File" and "Email" in the same settings, I could not find the way how to differentiate them (e.g. Use "File" when executed from new menu item. Use "E-mail" when executed during shipping)
