Hi
I have set up a workflow for purchase orders, specifying that if the change in the value of the PO (line or total) is greater that 10% (new value-last value on po), the po should be approved as per the hierarchy set up. However, if the change is less than 10%, the po does not need to be approved through the workflow.
In terms of control, a user can make several changes (of less that 10%) to the PO value, resulting in a major change without any approval.
Is there a way to validate against the original value of the PO i.e. the cumulative change in the PO is validated against the parameter of 10%?
