Compounding Info Object

In Compounding a Field or another Object is attached to an Info Object. A Compounding Characteristic is when object's definition is incomplete without the definition of the another Characteristic Info Object.


For the better understanding the Info Object - Location (0PP_LOCAT) has to be assigned with  a Compound Info Object - Plant (0PLANT).


Here Plant(0PLANT) is the Superior Info Object of the Location(0PP_LOCAT)


The Info Object 0Plant has to be Installed/Created/ Activated first, later followed by Location(0PP_LOCAT)


While creating the Info Object itself we need to assign the Superior Object like below at Compounding Tab Page of Info Object.

Compounding Info Object Acts as a compounding Primary Key at the Master Data Table.

When a compounded Info object is included in an Info cube, all corresponding info objects are added to the Info cube. 


If Location(0PP_LOCAT) is to be included in the Info Cube , Plant (0Plant) is automatically added to the Info Cube. 




When a Compounded Info object is included in the DSO , all corresponding Objects are added to the DSO Key fields/Data Fields.


If Location(0PP_LOCAT) is to be included in the DSO , Plant (0Plant) is automatically added to the DSO. 


The below video explains: 

If an info object is defined as an attribute, it cannot be included as compounding object.




The total length of the compounding info objects cannot exceed 60 characters.


An Info Object which is defined as an Attribute only setting can not be included in Compounding object.


The Compounding Info Objects at BEx Report out put will be 0PLANT/0PP_LOCAT.

Surrogate ID -- Master Data Tables

Standard Info cube consists of fact table surrounded by many dimension table. SID table links these Dimension tables to master data tables.

SID is surrogate ID generated by the system. The SID tables are created when we create a master data IO.  In SAP BI Extended star schema, the distinction is made between two self contained areas: Info cube & Master data tables and connecting SID tables.

The master data doesn't reside in the Extended Star schema but resides in separate tables which are shared across all the star schemas in SAP BI.

An Unique Numeric ID , the SID is generated which connects the dimension tables of the infocube to that of the master data tables.

The dimension tables contain the DIM IDs and SIDs of a particular Characteristic Info Object. Using this SID Table the Master data ( attributes and texts of Info Object) is accessed.

 List of Technical Tables  

F  - Fact Table - Uncompressed Fact Table - Contains Direct data for cube Request wise ( Based on B-Tree Index ) 
E  - Fact Table - Compress cube - Contains compressed data without Request IDs( Request ID would be 'zero') ( based on  Bitmap Index )    
M - View of Master Data Table  - /BI0/MMATERIAL

P - Time Independent Master Data Table - /BI0/PMATERIAL
Q  - Time Dependent Master Data Table - /BI0/QMATERIAL

H - Hierarchy table  - /BI0/HMATERIAL
J  - Hierarchy interval table  - /BI0/JMATERIAL

K - Hierarchy SID table - /BI0/KMATERIAL

I  - SID Hierarchy structure      - /BI0/IMATERIAL
S  - SID table  - /BI0/SMATERIAL

X - Time Independent SID table for Attr - /BI0/XMATERIAL
Y  - Time Dependent SID table fir Attr  - /BI0/YMATERIAL

T  - Text Table - /BI0/TMATERIAL 
   

SID -- Master data Tables

Surrogate Keys are automatically generated uniform keys, which are uniquely identifying specific real-world key values. 


SID are only the connectivity link between DIM IDs and Master Data Tables .


Let us take an Example of a Material Master Data Tables and understand the various connectivities with SID table.
