Using table maintenance generator in BDC rec , BDC_OKCODE getting lost??

For a custom table a view is created using a table maintenance generator. It is created to populate the custom table through BDC recording.

On executing this recording, for the first recording only the BDC_OKCODE is getting lost on the second screen. So, the table is not getting populated.

So, how to ensure that the BDC_OKCODE is not lost on the second screen when using a table maintenance generator??
