Data entity: How to get to embedded data source

Posted on by Community Member

I tried to get to CustInvoiceLine data source in FreeTextInvoiceEntity, the top data source is CustInvoiceTable. I assume getBuffer() in DataEntityDataSourceRuntimeContext can only get to the top level data source, which is CustInvoiceTable in this case, how could I get to CustInvoiceLine so I can populate more vales using event?

public static void FreeTextInvoiceEntity_onMappedEntityToDataSource(Common _sender, DataEventArgs _eventArgs)
{
DataEntityContextEventArgs entityContextEventArgs = _eventArgs as DataEntityContextEventArgs;
DataEntityRuntimeContext entityCtx = entityContextEventArgs.parmEntityContext();
DataEntityDataSourceRuntimeContext dataSourceCtx = entityContextEventArgs.parmEntityDataSourceContext();

CustInvoiceTable custInvoiceTable = dataSourceCtx.getBuffer();

// How to get to CustInvoiceLine from here?????

}

MappedEntityToDataSource gets called for each datasource on the entity , so you have to write following code

if (_dataSourceCtx.name() == dataEntityDataSourceStr(FreeTextInvoiceEntity, CustInvoiceLine )) { CustInvoiceLine CustInvoiceLine = _dataSourceCtx.getBuffer() }

Like Sukrut said, in your case, it should come twice into method FreeTextInvoiceEntity_onMappedEntityToDataSource for CustInvoiceTable and CustInvoiceLine data sources. Is it not happening in your testing? you can put breakpoint and see behavior to understand the flow.

Hi Yvonne

As mentioned already - MapEntyToDataSource is called for each datasource. This is the case for all DE methods that has a DataEntityDataSourceRuntimeContext parameter (under correction).

I suggest that you use a switch statement (as suggested by BP):

switch (_dataSourceCtx.name()) { case dataEntityDataSourceStr(DEName,DEDatasourceName): //your logic break; case dataEntityDataSourceStr(DEName,OtherDEDataSourceName): //your other logic break; }

For interest sake - your line CustInvoiceTable custInvoiceTable = dataSourceCtx.getBuffer() will throw an error when another dataSource gets processed.

And then if you need to access a DE dataSource other than the one currently being processed, you may use _entityCtx.getRuntimeContextByName()

DEDataSourceTable currentRecord = _dataSourceCtx.getBuffer(); DEOtherDataSourceTable otherRecord = _entityCtx.getRuntimeContextByName(dataEntityDataSourceStr(DEName,DEOtherDataSourceName)).getBuffer();

Lastly - you are making your life difficult by using event handlers and not CoC.

[ExtensionOf(dataentityviewstr(FreeTextInvoiceEntity))] final class FreeTextInvoiceEntityXYZ_Extension { void mapEntityToDataSource(DataEntityRuntimeContext _entityCtx, DataEntityDataSourceRuntimeContext _dataSourceCtx) { next mapEntityToDataSource(_entityCtx, _dataSourceCtx); CustInvoiceTable custInvoice; switch (_dataSourceCtx.name()) { case dataEntityDataSourceStr(FreeTextInvoiceEntity,CustInvoiceTable): custInvoice = _dataSourceCtx.getBuffer(); //your logic break; case dataEntityDataSourceStr(FreeTextInvoiceEntity,CustInvoiceLine): CustInvoiceLine custInvoiceLine = _dataSourceCtx.getBuffer(); custInvoice = _entityCtx.getRuntimeContextByName(dataEntityDataSourceStr(FreeTextInvoiceEntity,CustInvoiceTable)).getBuffer(); //your logic break; } } }

Good luck!
