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 Validation (Using BADI)

Image
In this blog, we will see how to validate the MDG attributes using the BADI implementation. So, we are taking the example of the 'BP Grouping' field to make it mandatory on the UI. For this, we should know the technical attribute name for the respective field. In our case, 'BU_GROUP' is the technical name for the BP grouping field. Steps for the Implementation of Validation BADI. 1.   Open T-code ‘MDGIMG’ –> General Setting -> Data Quality and Search -> Business Add-Ins -> Execute BADI: Define Validation/Derivation OR SE18 -> BADI name: 'USMD_RULE_SERVICE' -> Create BADI Implementation.  2. After execution, the following screen will appear. Go down, and there you will find the option to create enhancement implementation. Click on that button. 3. Provide the name and short description of the implementation, as follows:   4.  After that, we have to create the BADI Implementation and Implementation class. 5.  You will be directed to the Enha...

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...
