Help required: characteristic values of material

Hi all,

My requirement is to print description of the articles shipped.

The print program is RVADTR00 (print prg for transaction VT02N)

The description of articles means the characterstics

The logic mentioned is as follows:

(Go to KSML, for class# XXXX, to get the internal characterstic KSML-IMERK.

Use IMERK to get all the characterstic values from table CAWN, CAWN-ATWRT)

Now my question is, does the standard program retreive these values into any structure.

Else, do I have to use the above mentioned logic, If yes can you tell me if

there are any standard function modules to find the characterstic values of the class to

which the material belongs.

Thanks
