Our parameter is 'EX' instead of '01' key, so no chance of mistake there.
The issue is actually happening with another default value (from the Price Adoption tab), not with the Info record update indicator. I was just trying to maintain the example given in this thread.
I expect the same logic to apply.
If the user has EVO = EX, when he/she tries to create a PO, SAP keeps adopting the previous purchase order price conditions.
SAP stops doing this when I change the value to "Do not copy" in the blank ' ' default value key, even though the user still has EVO parameter = EX
Thanks foy your input.
