The IDoc structures MATMAS03 and CLFMAS01 will be delivered by Intergraph with interface. It is helpful or necessary to pre-allocate special IDoc fields using default values. You should do this step at this point.
Furthermore ,you can determine by setting the Master Data and Plant Dependent check boxes if an IDoc field on screens SAP 10.05 Master Data Mapping (Master Data check box on SAP 10.03) or SAP 10.06 Master Data Mapping (Plant Dependent) (Master Data check box and Plant Dep. check box on SAP 10.03) will be displayed in the LOV or not.
All fields that are "not absolutely meaningful" were deactivated by Intergraph with delivery. This applies particularly for the settings regarding the plant dependent IDoc fields (Plant Dep. check box on SAP 10.03).
