TB,elastic

Hi friends;

I am doing modal analysis for functionally graded material in APDL ANSYS. equation of material properties has three independent variables,(x,y,z), and element type is solid186. I used from function tool for loading equation then saved it as table, hereinafter I used from TB 

command:

TB,elastic,1,,,,,%hh%

hh is table name.

warning message was created: "the function or table specification hh for material number 0 is currently allowed for joint element material specification. The TB command is ignored.

what's problem? how can correct it?

please help me.

picture of my warning is attached below.

Regards.
