Hi @varshinims08
Thank you for posting.
According to your description, you would like to use flow to update your table based on number column.
But I’m confused about your request related to link this two records which has same number value. What do you mean by link both the records together? Could you please show me an example ? Thanks in advance.
By the way, the flow you required would like as below:
length(outputs('List_records_(deprecated)_2')?['body/value'])
Following up the flow provided, when expression returns true. It means the new created record is the first record that contains this number.
When you get false from expression, it means, the record with same number already exists.
If you want to link two records, please configure link action in no branch.
