In Split Valu the Global setting for Ext POs is set to 2- External Purchase order allowed. I would like to set the Local Definition/Valuation Type to 0-No external Purchase Orders Allowed. I can't seem to do that. I select the Plant go to Change, Select 0, hit Save. The info message is "No Changes made. The Global Definitions show up at the bottom. When I go back to the list of Valuation Types the Ext. Po setting is still 2.
Is the Global setting overriding the Local? If so, what are my options as I don't want to change the Global settings.
