Re: Sceduling agreement referencing a value contract (kw)

I know it's possible with value contract WK. But in that case, I should use PO every time I need a service. Volume of data generated in that case is higher. I'm aiming to reduce the flow by creating just delivery calls (ME38).
Now the problem that I have when I try to define a SA based on value contract is that system shows me an error telling me that SA based on contact can be defined only for SA with temporal conditions knowing that I have already defined the period of validity and discount terms.
