Ability to stop POs from being converted if the total IRF committed amount exceeds the approved IRF amount?

@samulofl not sure what field you are referring to by IRF, Im not familiar. 

However, by looking at your scenario, I wonder whether you can use the functionality of workflow (IFS cloud) or also custom events (also in APP10 and earlier) to cater this requirement. 

Sorry I should rephrase, the max amount on the Project.

This is what we want to put a cap on, when PO’s are created
