This should be an easy one for y’all. On Approval workflows, if every employee needs an approval for a PO, then should every lower employee have 0 as the purchase limit and purchase approval limit, and then their superior would also have 0 purchase limit but a greater approval limit? The superior will also need to have their own POs approved. Basically, what is the setup so no employee can approve their own PO?

make it more simple put 0 for everyone's purchase limit and just use the purchase approval limit to build your approval hierarchy. By making the purchasing limit 0 will force everyone to get approval from their approver. If you have a value in purchase limit then that employee doesn't need any approval as long the stay below the threshold. This should work everyone needs to get approval. other option is to use conditions in workflow to disallow creator from approving their own transactions.

Thanks Sam! That was it!
