Hi there @preeti5,

welcome to KNIME Community!

To my knowledge there can not be data table without row id column.Why is having different id problem? What node(s) are you using? You can always use RowID node to “reset” row ids on both tables and then they’ll be same.

Hi @preeti5 and welcome to the KNIME forum,

If you are using the Column Appender node to merge 2 (or more) tables, you can use the “Generate new row keys” option in the node’s configuration window instead of the default option to bypass row ID check.
