Profit Center Mandatory

Hi,

I made profit center mandatory for ROH material type in OMS9

It is optional for MM01,2,3

The profit center appears in SALES-Plant storage-costing view and is mandatory

When i am trying to create material with basic1,2 and purchasing view system is asking for profit center

My requirement is Profit Center should be mandatory only when that particular view is selected

Is there any solution for this issue?

Thanks
