Notes about "Reference Material"
See REFMAT_:MMS – Access to data of a reference material for a definition of "reference material".
The reference material and if required the keys from material views to access must be made available to ProMaterialData. This can be made using own code before the ProMaterialData integration using the class /PRONOVIA/CL_MMS_REFMAT_DATA (see Integration and Enhancement Manual) or automatically by using this settings.
