JSON import of products and variants fails

Hello forum,

- having a DW9.10.14 to import a JSON file will fail, if not all "EcomProducts" fields are present on the variant. In this ex. "unitprice" + "unitcurrency" are only relevant for the product.

Log:
Import job failed: The source reader for the table: [EcomProducts] can not get a value for the column: [unitprice].The input row is:...

Is there anyway I can bypass the requirement for adding the fields to the variant?

 

PS. Doing the same with a XML file will work fine.

 

Below is a snippet of the JSON:

    {
        "tableName": "EcomProducts",
        "EcomProducts": [
            {
                "productid": "ZXY111",
"productvariantid": "",
                "productlanguageid": "LANG1",
                "productdefaultshopid": "",
                "productnumber": "ZXY111",
                "productname": "Chair (product)",
                "unitprice": "357.00",
                "unitcurrency": "EUR"
            },
            {
                "productid": "ZXY111",
"productvariantid": "fabric_643.cover_oak.base_black",
                "productlanguageid": "LANG1",
                "productdefaultshopid": "",
                "productnumber": "ZXY111",
                "productname": "Chair (variant)"
            }
        ]
    }

Hi Michael,
it works in the XML Provider because of the differences in the implementation in those two providers. The XML provider auto fills the not present columns with a null value,
but this is not implemented in the JSON provider. As a workaround you can try to use JSON->XML provider job and then use XML Provider->Your destination provider job
or implement a custom table script that can add the missed row column values at the runtime and use that table script in the JSON -> Your destination provider job.
You can read more about Table Script implementation here.
The sample pseudo code that can fill the missed columns may look like this:
 foreach (ColumnMapping cm in mapping.GetColumnMappings().Where(cm => cm != null && cm.Active && cm.SourceColumn != null))
                {
                    if (!row.ContainsKey(cm.SourceColumn.Name))
                    {
                        row.Add(cm.SourceColumn.Name, null);
                    }
                }

Thanks for your feedback Dmitrij, think the way forward is the Table Script implementation, but it would have been lovely, if XML and JSON provider followed the same implementation.
