Generate approvals based on a customized list field

[Sanu Giri]

I have a field 'approver' which store user name in comma separated. I want when user make any changes in that field 'approver' approvals will be generated based on that field for problem table in flow designer.

What's your question? You can create a flow or business rule to create the approval records for the users in that field. Just know that making changes to that field, after approvals are already created, makes little sense, process wise.
