Restrict a PO upon creation based on vendor code (one time vendor)
Is there a way to restrict a PO upon saving/entering an item value that will make the total PO value exceed a certain amount to a specific vendor (in my case I will use it for one time vendors) w/o using any user exit?
I did some reading online and saw that usually a user exit is suggested for these kinds of requirements, but I am just curious of the options that can be considered for this type of scenarios. I am thinking of adding release but don't think it's practical as we already have a release in our system that doesn't involve vendors.
Thank you for the help!
