Unlocking SAP MDG: Essential APIs and BAdIs for Custom Enhancements and Integrations

 SAP Master Data Governance (MDG) offers several APIs and BAdIs (Business Add-Ins) to extend and customize its functionality. These tools enable you to integrate MDG with other systems, implement custom business logic, and enhance the data governance processes. Below is an overview of important SAP MDG APIs and BAdIs:

SAP MDG APIs

1. Data Replication Framework (DRF) APIs:
• Used for replicating master data to other systems.
• Example: DRFOUT transaction to set up and manage replication models

CALL FUNCTION 'DRF_REPL_MASTER_DATA'

  EXPORTING

    iv_model_name     = 'MDG_REPL_MODEL'

    iv_source_system  = 'SOURCESYSTEM'

    iv_target_system  = 'TARGETSYSTEM'

  TABLES

    it_objects        = lt_objects

  EXCEPTIONS

    replication_error = 1

    OTHERS            = 2.

            2.  MDG Change Request APIs:

• For creating, updating, and processing change requests.
• Example: API for change request management

DATA: lt_change_request TYPE TABLE OF usmd1200.

CALL FUNCTION 'API_MDG_CR_CREATE'

  EXPORTING

    iv_cr_type        = 'MDG_CR_TYPE'

    iv_entity_name    = 'ENTITY'

  IMPORTING

    et_cr_header      = lt_change_request

  EXCEPTIONS

    OTHERS            = 1.

 

3. MDG Data Model APIs:

• Managing and interacting with MDG data models.
• Example: API for fetching entity data

DATA: lt_entity_data TYPE TABLE OF mdg_entity_data.

CALL FUNCTION 'MDG_READ_ENTITY'

  EXPORTING

    iv_entity_name   = 'ENTITY_NAME'

  TABLES

    et_entity_data   = lt_entity_data

  EXCEPTIONS

    OTHERS           = 1.

 

4. MDG Consolidation and Mass Processing APIs:

• APIs for mass data consolidation and processing.
• Example: API for initiating consolidation tasks.

 

CALL FUNCTION 'MDG_CONSOLIDATE_DATA'

  EXPORTING

    iv_task_id        = 'TASK_ID'

  EXCEPTIONS

    consolidation_error = 1

    OTHERS              = 2.

 

SAP MDG BAdIs

1. BAdI for Custom Validations and Derivations:
• USMD_RULE_SERVICE: Used to implement custom validation and derivation logic.

METHOD if_usmd_rule_service~execute.

  LOOP AT it_data ASSIGNING FIELD-SYMBOL(<fs_data>).

    IF <fs_data>-attribute_name = 'YOUR_ATTRIBUTE'.

      IF <fs_data>-attribute_value IS INITIAL.

        APPEND VALUE #( entity = <fs_data>-entity

                        attribute = <fs_data>-attribute_name

                        message = 'Value cannot be empty' ) TO et_messages.

      ENDIF.

    ENDIF.

  ENDLOOP.

ENDMETHOD.

 

2. BAdI for Change Request Processing:

• USMD_CREQUEST: Used to enhance the change request process

METHOD if_usmd_crequest~process_request.

  " Custom logic for change request processing

  LOOP AT it_cr_data ASSIGNING FIELD-SYMBOL(<fs_data>).

    " Process each change request data entry

  ENDLOOP.

ENDMETHOD.

3. BAdI for Data Replication:

• DRF_REPLICATION_FILTER: Used to filter and enhance the data replication process

METHOD if_drf_replication_filter~filter_data.

  LOOP AT it_data ASSIGNING FIELD-SYMBOL(<fs_data>).

    IF <fs_data>-attribute_name = 'YOUR_ATTRIBUTE' AND <fs_data>-attribute_value = 'FILTER_CONDITION'.

      DELETE it_data.

    ENDIF.

  ENDLOOP.

ENDMETHOD.

4. BAdI for UI Enhancements:

• USMD_UI_EVENT2: Used to enhance user interface events in MDG

METHOD if_usmd_ui_event2~process_event.

  " Custom logic for UI event processing

  CASE iv_event_id.

    WHEN 'CUSTOM_EVENT'.

      " Handle custom event

  ENDCASE.

ENDMETHOD.

BAdI for Data Import and Export:

• USMD_ACC_FI_BS_DATA: Used for custom data import and export functionalities.

METHOD if_usmd_acc_fi_bs_data~process_data.

  " Custom logic for data import/export

  LOOP AT it_data ASSIGNING FIELD-SYMBOL(<fs_data>).

    " Process each data entry

  ENDLOOP.

ENDMETHOD.
