Adding Zfield in MDG -S Data Model

$

Hello Experts,

 

I have gone through the standard guide for MDG-S and MDG-C to ehance the Data Model ( Reuser Option).

Say for example if I have to add a field/attribute  ZZ_License in BP_CENTRL entity.

This fields has to be added in both BP and Vendor tables.Below are my doubts :

 

1: So, in which case i should go for SMT mapping and when should  I  write the code in Handler class method ( Map to 2 API).

Difference between these 2 approaches.

 

 

2: When we extend the Data Model, as per the standard document , we need to extend the field in 2 structures

For Vendor

VMDS_EI_VMD_CENTRAL_DATA

VMDS_EI_VMD_CENTRAL_DATA_XFLAG

 

Why we need to extend the filed in these 2 structures since we already appended the field in LFA1 table.

What is use of these 2 structures  and difference between  VMDS---Data and VMDS----Xflag?

 

For

BP

CI_EEW_BUT000 and CI_EEW_BUT000_X

 

 

Why we need to extend the filed in these 2 structures since we already appended the field in BUT000 table.

What is use of these 2 structures  and difference between  CI---BUT000 and CI----X ?

 

 

 

 

 

Regards

Vishal
