Restric values on PI Sheet characteristic
I'd like to know if there is a way to restrict the values in a drilldown of a filed in reference on another field on PI sheet.
On PI sheet there are 2 fields. First is CAR and second is COLOR.
On this 2 characteristics there are several values defined on o26c.
For CAR there are: Ferrari, Aston and VW.
For Color there are: yellow, green, red and black.
What I need is if the user chooses Ferrari in CAR characteristics. The char COLOR display only the colors yellow and black on the drilldown... so on...
There is a way to do that?
I Thought I could do that using functions on the characteristic, but I do not think it works...
