Business Context: Often business requires an additional data or information which are not fulfilled with standard fields available in object master data provided by SAP. At times that information might be needed in the transactions related to the object master data for example additional data for Equipment master like PO Number, which might be needed in the related maintenance notification or Maintenance order and in the related reports.
Solution: With SAP S/4HANA Key User Extensibility , we can add additional custom fields to technical objects and expose the fields on Fiori Screens with simple component configuration. It helps the business to simplify the addition of required information on the technical objects easily by self-enabling the custom fields.
This blog will focus on how to create custom fields for technical objects, extending the custom field to required UI Reports and enabling business scenarios. In this context, the following business scenario are available for Maintenance Notifications.
Transfer the custom field data from a maintenance notification to a maintenance order by enabling the business scenario EAM_NTF_TO_ORD.
Transfer the custom field data from an equipment to a maintenance notification by enabling the business scenario EAM_EQUI_TO_NTF.
- Transfer the custom data from Functional location to a Maintenance Notification by enabling the business scenario EAM_FL_TO_NTF
