public void initializeEntityDataSource(DataEntityRuntimeContext _entityCtx, DataEntityDataSourceRuntimeContext _dataSourceCtx)

{

super(_entityCtx, _dataSourceCtx);

if (_dataSourceCtx.name() == “SalesTable”)

{

// Custom logic here

}

Before

Correct Incorrect Correct answer

After

Correct Incorrect Correct answer

Simultaneously

Correct Incorrect Correct answer

It replaces initializeDataSources

Correct Incorrect Correct answer

If updateEntityDataSource returns false, what does this typically indicate to the framework?

The record was updated successfully.

Correct Incorrect Correct answer

The update was skipped or failed, and the framework should stop.

postTargetProcess (checking for end of batch)

Correct Incorrect Correct answer

mapEntityToDataSource

Correct Incorrect Correct answer

validateField

Correct Incorrect Correct answer

Why is initializeDataSource noted as being called “once for each DataSource in Entity”?

Because entities can only have one datasource.

Correct Incorrect Correct answer

To ensure every joined table buffer is properly prepared before mapping begins.

Correct Incorrect Correct answer

It is a bug in the standard framework.

Correct Incorrect Correct answer

updateDataSource eventually triggers validateWrite of the table. If validateWrite returns false:

The entity method ignores it and saves anyway.

Correct Incorrect Correct answer

The transaction is usually aborted, and an error is thrown.

Correct Incorrect Correct answer

The postLoad method is triggered to fix the data.

Correct Incorrect Correct answer

The record is skipped and moved to a separate table.

Correct Incorrect Correct answer

You see the following in a call stack:

DataEntity::update -> DataEntity::doUpdate -> DataEntity::persistEntity

What comes immediately after persistEntity?
