    You will now use Core Data Services to create a table. You will then use other entities to combine the data.

    Begin by creating a folder under db->src:

    You can now explore the graphical Core Data Services editor briefly.

    Right-click on the entity and choose Graphical Editor.

    Double-click on the context to create an entity:

    create CDS

    Click on an entity and drop it in the editor:

    create CDS graphical

  • Step 4

    You will now add data into your new entity. Build the db module first:

    Build db

    Create a comma-separated values file called status.csv in the data folder:

    create csv

    Add the following contents to it:

    I, In process
    A, Approved
    R, Rejected

    Save the file.

    create csv

    Now you need to add a new file to indicate how that file loads your new table. Create a file called load.hdbtabledata

    create csv

    Add the following contents to it:

        "format_version": 1,
        "imports": [
                "target_table": "PO.APPROVAL_STATUS",
                "source_data": {
                    "data_type": "CSV",
                    "file_name": "status.csv",
                    "has_header": true
                "import_settings": {
                    "import_columns": [


    load csv

    Build the module.

    Build module

    Save and build the db module. Wait until the build finished to answer the following question.
