Hi @Ramya Ranjan Sahu ,
As per my knowledge, I'm afraid it is currently impossible. Generally, we have “Get changes to an item or file (properties only) action” to get the exact set of changes that might have occurred to a list. The action outputs helpful tokens such as “Has Colum Changed:<Column name>” that can be used to filter your flow to just the column(s) you care about. However, Attahcments column is not included in this action. So I'm afraid this is not supported by Microsoft Power Automate flow and you can post your feedback here: https://powerusers.microsoft.com/t5/Microsoft-Power-Automate/ct-p/MPACommunity.
