Vast is an Ocean,So is vast the World of Knowledge. With my diving suit packed, loaded with imaginative visions, and lots of curiosity, started diving deep into the world of BODS.Lots of work is going on. Got attracted towards the “Key_Generation” transform and was fascinated at its features.Now it was time for me to fuse and adapt myself into its world.

An example is the surrogate key of the target table. The Table Comparison does get the logical primary key as input, tries to find the matching row in the comparison (target) table and if found, will get all the missing column values as well like the corresponding KEYID. SAP BODS - Transforms Types - Transforms are used to manipulate the data sets as inputs and creating one or multiple outputs. There are various transforms, which can be used in Data Services.

KeyGeneration; Show Answer. 21) You want to join a “sales”, “customer” and “product” table. Each table resides on a different data store and will not pushdown to one SQL. Jun 24, 2012  A surrogate key is an auto generated value, usually integer, in the dimension table. It is made the primary key of the table and is used to join a dimension to a fact table. Among other benefits, surrogate keys allow you to maintain history in a dimension table.

THE KEY_GENERATION TRANSFORM:-

What Is Bod In Construction

This transform is categorized under the “Data Integrator Transforms”. This generates new keys for source data, starting from a value based on existing keys in the table we specify.

If needed to generate Artificial keys in a table, the Key_Generation transform looks up the maximum existing key value from a table and uses it as the starting value to generate new keys.

The transform expects the generated key column to be part of the input schema.

STEPS TO USE KEY GENERATION TRANSFORM:-/c-license-key-generator-example.html.

Scenario:- Here the target data source for which the keys is needed to be added, have certain newly added rows without a Customer_ID. This could be easily understood in the following snap:-

Our aim here is to automatically generate the keys(Customer_ID) in this case , for the newly inserted records which have no Customer_Id. Accordingly we have taken the following as our input (the modified data without Customer_ID)

INPUT DATA (to be staged in the db):-

TARGET TABLE(which contains the data initially contained in the source table before the entry of new records in the database):-

THE GENERATED DATA FLOW:-

CONTENT OF SOURCE DATA:- (containing the modified entry alone)

CONTENT OF QUERY_TRANSFORM:- Dialect does not support identity key generation confluence.

CONTENT OF THE KEY_GENERATION TRANSFORM:-

THE CONTENTS OF THE TARGET TABLE PRIOR JOB EXECUTION:-

The JOB_EXECUTION:-

THE OUTPUT AFTER THE JOB EXECUTION:-

We can now see from the output how Keys have been generated automatically to those records which did not have the Customer_ID initially.

I explored this little process of the Key_Generation transform, and it seems a savior at times when huge amount of data have the missing entries(wrt to the keys or any sequential column fields).

Now its time to go back to the surface of waters…….
