MEINS problem in BAPI_MATERIAL_SAVEDATA

Hi ,

I am using the BAPI_MATERIAL_SAVEDATA to create a material.

And I am passing the MEINS ( Base Unit of Measure) values from my table, but here I am getting the following error "not a valid unit of weight". I heared that there is a function module which is used to convert the MEINS values internaly for BAPI.

How to resolve this issue?? pls help.

Thanks,

Sridhar.
