Step 4: Load data into your entity

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.
