Object Level
Data Lineage at Object level for DDIC Entities.
We export two files: one file with all the relations of DDC Entities (“Relations”) and one file with more details (e.g. Technical Name and descriptions) (“Details”) of the entities.
In the “Relations” file only entities are included that have a connection in the data lineage. E.g. a View with its base tables.
The supported entities for the Object level are the following:
-
Tables
-
Views/CDS Views
-
Function Modules
-
Transactions
-
Data Sources/Extractors
-
ABAP Class
-
ABAP Program/Report
-
Domain
Details
In the Details file, we also identify CDS Data Definitions.
These parameters are displayed per object:
-
Object ID
-
Technical Name
-
Object type
-
Data Definition (only for CDS Views)
-
Subtype (only for Tables)
-
Development class
-
Component
-
Language dependent Description
Relations
In the “Relations” file, only entities connected in the data lineage are included, e.g., a View with its base tables.
This information is displayed:
-
Nodes: ID of Objects with a relation to another
-
Edges: Relation ID, ID of Source and Target Object.
Field Level
Data Lineage at Field level for DDIC Entities.
Three files are exported: one file with the buildup of DDIC entities (“Buildups”), one with the descriptions of the fields (“Buildup Descriptions”), and one file with the mappings between the fields (“Mappings”).
Buildup
The fields and their parameters are displayed per objects like this:
-
Parent ID
-
Field ID
-
Technical name
-
Data type
-
Length
-
Decimals (for data types DEC, CURR, QUAN & FLTP)
-
-
Buildup Descriptions
The Buildup Descriptions file lists the IDs and descriptions of all fields.
Mappings
In the “Mappings” file, only fields connected in the data lineage are included.
This information is displayed:
-
Nodes: ID of fields with a relation to another
-
Edges: Relation ID, ID of Source and Target Field.
Parsing the ABAP Code
Wit the S/4HANA connector it is possible to scan the ABAP code too. We identify which ABAP code is calling other ABAP codes. We also find out which tables are modified and which are read by the ABAP code. This is how we map a data lineage. Here you can find a list of key words which are identified in ABAP code.
