Sample: Import data using complex data map
This sample shows how to create new records by using data import. The sample uses a complex data map. You can download the sample from here.
The source data for this sample is contained in the following file
How to run this sample
- Download or clone the Samples repo so that you have a local copy.
- (Optional) Edit the cds/App.config file to define a connection string specifying the Common Data Service instance you want to connect to.
- Open the sample solution in Visual Studio and press F5 to run the sample. After you specify a connection string in cds/App.config, any sample you run will use that connection information.
If you do not specify a connection string in cds/App.config file, a dialog will open each time you run the sample and you will need to enter information about which Common Data Service instance you want to connect to and which credentials you want to use. This dialog will cache previous connections so that you can choose a previously used connection.
Those samples in this repo that require a connection to a Common Data Service instance to run will include a linked reference to the cds/App.config file.
How this sample works
In order to simulate the scenario described above, the sample will do the following:
- Checks for the current version of the org.
ImportMapmethod creates an import map.
ColumnMappingmethod creates a column mapping for a
EntityReferencemethod relates the column mapping with the data map.
LookUpMappingmethod creates a lookup mapping to the parent account.
ImportFilemethod creates a import file.
GetHeaderColumnsImportFileRequestmethod retrieves the header columns used in the import file.
ParseImportRequestmethod parses the import file.
RetrievedParsedDataImportFileRequestmethod retrieves the data from the parse table.
TransformImportRequestmethod transforms the import.
Display an option to delete the records created in the Setup.
The deletion is optional in case you want to examine the entities and data created by the sample. You can manually delete the records to achieve the same result.
