SAP MDG Process Modelling

Image
Overview In SAP MDG, every change to master data is initiated using a change request. After a change request is initiated, it needs to be processed before activation or rollback by applying governance rules and collaborations. The process model provides the required input (metadata) for change request creation and processing, e.g., workflow, CR steps, and objects that can be processes. Submit and activate/rollback are mandatory steps in a change request. MDG reuses the SAP Business Workflow component of an underlying SAP business suite. SAP MDG workflow is an instance of SAP Business Object BUS2250. If the request has parallel processing, then each parallel step of the change request will have one BUS2250 instance. Define Governance Scope: Here we can define governance scope on the entity as well as the attribute level. For example, we have kept ‘NO’ to the below custom entity. As a result of MDG UI, the UIBB for this entity will only be in read-only mode. Business Object An ...

Extend the MDG Business Partner – Node Extension (Reuse Option)

Image
So, here we are going to add a new entity to the company code data level, as shown in the above figure. Steps:- Extension of S4 API Structures To get the API structures, we need to go to the standard BP handler class. In Below structure, we need to add our own API structure. Class ‘ CL_MDG_BS_ECC_HANDLER ’. Table Type ‘ MDG_BS_BP_TT_ECC_EXTERN ’. Data Dictionary Object Creation Structures For Genil model extensions: Creation of Table to store this Secret number data in backend active table Extension of BP data model with new Entity Generate Data Model specific structures Create and Implement BP Handler Class Below methods we need to re-define GET_OBJECT_DATA_BY_ENTITY SORT_ENTITIES MAP_DATA_2API MAP_DATA_2STA PREPARE_EI_HEADER_MAP_2API READ_OBJECT_DATA SAVE_ADDITIONAL_OBJECT_DATA CONSTRUCTOR Below methods we have created newly READ_VENDOR_BY_LIFNR READ_VENDOR MAP_BP_ZSECRET_N_2API MAP_BP_ZSECRET_N_2STA CONSTRUCTOR METHOD  constructor .    ...

MDG Derivation (BADI)

Image
In this blog, we will see how to derive MDG attributes using BADI. Derivations can be divided into two types.  Single-entity derivation:  Automatically populating some attribute value in one entity based on an attribute value from same entity. For this, we use 'USMD_RULE_SERVICE' BADI definition. Cross-entity derivation:  Automatically populating some attribute value in one entity based on an attribute value from another entity. For this, we use 'USMD_RULE_SERVICE_CROSS_ET' BADI definition. First, we will see a single entity derivation. Scenario:  We are going to make language English as the default if the user gives the country as India. Steps: 1. Go to SE18. 2. In 'USMD_RULE_SERVICE' BADI defination, create BADI Implementation.  3. For creating BADI Implementation, first we need to create Enhancement Implementation.  4. Give the properties as below. 5. Now, create BADI Implmentation and give following properties. 6. Maintain the filter values. H...
