In PS field RESBD-GPREIS cannot be made mandatory but can in PM

Question

The feild RESBD-GPREIS can be made mandatory in PM but it does not take effect in PS and the field is not available in PS config.  I have tried
SPRO>IMG>Project Systems>Structures>Operative Structures>Networks>User interface settings --> Define field selection for networks --> Field selection :Network:Details -->
without luck.   Has anyone been able to make Price mandatory for Purchasing tab in PS?   We can make external processing using AFVGD-PREIS

In general in Web Dynpro ABAP, setting the required property on the UI doesn't actually do anything except visibily mark the UI element with the required symbol (the red * next to the label).  Unlike classic dynpro, this property doesn't cause a runtime check to see if the field has a value or produce an error message.  This must be added within the application logic.  There is a helper method cl_wd_dynamic_tool=>check_mandatory_attr_on_view.
That said, I can't comment specifically about this SRM framework.  It would be something application specific that sits above the WD framework.  Perhaps it has this dynamic call already built in and this situation is an error.  Or it could be the case that the SRM tool is just exposing all the UI element properties and you would have to use the Enhancement Framework to extend the view logic to acutally perform a mandator check.
