Hi Joe,
The postLoad method can be used if you have also the original fields in your staging table. Then you can use something like this:
/// <summary>
/// Map data fields to virtual fields
/// </summary>
public void postLoad()
{
this.TableName = tableId2Name(this.Table);
this.FieldName = fieldId2Name(this.Table, this.Field);
this.ExtendedTypeName = extendedTypeId2name(this.ExtendedTypeId);
}When you need to map the virtual fields to the target datasource, you can use the method mapEntityToDataSource(). An example:
public void mapEntityToDataSource(DataEntityRuntimeContext _entityCtx, DataEntityDataSourceRuntimeContext _dataSourceCtx)
{
super(_entityCtx, _dataSourceCtx);
if (_entityCtx.getDatabaseOperation() == DataEntityDatabaseOperation::Insert || _entityCtx.getDatabaseOperation() == DataEntityDatabaseOperation::Update)
{
if (_dataSourceCtx.name() == dataentitydatasourcestr(MyEntity, MyTable))
{
MyTable myTable = _dataSourceCtx.getBuffer();
myTable.Table = tableName2Id(this.TableName);
myTable.Field = fieldName2Id(myTable.Table, this.FieldName);
}
}
}You can also use the metadata search for examples of entities in D365 which are also using these methods.
