Hi @Durga ,
Does this same error happen when using the smart client? Without being able to look at the xml for the screen, it sounds like there is missing metadata on that screen. Have you tried to see what records are null in the table field in cs_item. looking at for that it could point you to the problem item.
Best Regards,
Morris
Hi @Durga
This can happen due to mismatched or missing relationships in the metadata defined in the UI Designer. I suggest reviewing the relationships in the UI Designer and ensuring that the correct columns are added based on those relationships.
