There is a Idoc type EQUIPMENT_CREATE02 provided by SAP. This can be used to create the equipment master data. I have some additional data (like Warranty, Status and Partner Function ) which is not supported by this. I tried to create a extension for this Idoc type to grab the additional data but it is giving error "Action not possible for generated Idoc Types" Please let me , how can I enhance this Idoc Type in WE30 or any other transaction??
