Having above mentioned as scenario, I have used the below formula in expression background color,
if(([Supplier Payment Tracking]='On Time' or [Buyer Payment Tracking]='On Time' or [Shipment Document Tracking]='<5 Days' or [Lead Time Tracking]='<5 Days'), RGB(75,189,43)
,if(([Supplier Payment Tracking]='<7 Days' or [Buyer Payment Tracking]='<7 Days' or [Shipment Document Tracking]='5 to 7 Days' or [Lead Time Tracking]='5 to 7 Days'), RGB(254,187,48)
,if(([Supplier Payment Tracking]='>7 Days' or [Buyer Payment Tracking]='>7 Days' or [Shipment Document Tracking]='>7 Days' or [Lead Time Tracking]='>7 Days'), RGB(217,4,4))))
Now the issue is, I am not getting the desired color I want.
