Getting Dataset definition failed error for Gen2 operators

[TamasFodor]

Hi,

I have created a very simple workflow using Gen2 operators in SAP DI ( see screenshot 1 below). However when I go to specify Target folder under the 'Structure File Producer', I get an error as seen in screenshot 2. Looking at the error I tried restarting the Flowagent application from System Management but the error still persists. Anyone has faced a similar issue before? Any potential resolution?

It looks like you might not have specified a file name but a folder? Do the columns appear on the Structured File Producer configuration? Sometimes if you have not assigned the object in the Read Data from SAP operator before you connect it to the Structured File Producer, it does not bring over the column definitions (because they have not been defined yet). Check the filename (something like VBAP.csv or the format you chose) and that the columns are available for mapping. If they are not, you can delete the connection and re-connect the operators.

That’s correct jamesgiffin , I am specifying a folder in which I need to write the data as a parquet file.

The columns don’t appear in the Structured File Producer configuration. I can’t even see the mapping since it doesn’t allow me to select the Target in the Structured File Producer.

So should I be selecting a specific object , in this case VBAP table in the ‘Read Data from SAP’ operator? And then try to connect it with the Structured File Producer?

Tejas,

To rule out configuration/permissions, the connection is verified on the connection management tile and you can browse it in the metadata explorer. Also, you have to select the correct connection type. It looks like you have ADL in your path, but perhaps you configured it as ADL_V2, so you would need to select that option.

To rule out source configuration issues from ABAP - please ensure the correct notes are installed for generation 2 operators. Start here with the central note: https://me.sap.com/notes/2890171

Then you should configure the Read Data from SAP operator against the VBAP table (assuming this is SLT since it is a table). This action will read the VBAP metadata and make it available in the outbound port of the operator. Once you connect this port to the Structured File Producer, it should pull in the columns to map and allow you to configure the operator. See the screenshot below of VBAP in my instance:
