Providing code list extensibility

1. A computer implemented method for providing code list extensibility, the method comprising:

providing an external representation of a code data type, the external code data type representation having at least one external code value generated by a developer of at least one of a business object or a software suite for an existing business application and used by customers or software vendors;

providing an internal representation of the code data type, the internal data type representation having a second code value representation for the at least one internal code value, the internal code value representation including a unique identifier for the developer and is used by a database for the business application; and

mapping the external code data type representation and the internal code data type representation based at least in part on the unique identifier for the developer.

2. The method of claim 1 , wherein the second code data type representation accommodates an Advanced Business Application Programming (ABAP) namespace.

3. The method of claim 2 , wherein the unique identifier is an ABAP namespace prefix.

4. The method of claim 1 , wherein the unique identifier is a first unique identifier associated with a first software program associated with the developer.

5. The method of claim 4 , further comprising a second unique identifier associated with a second software program associated with the developer.

6. The method of claim 1 , wherein the external code data type representation further comprises an agency identifier, the agency identifier identifying the code value issuing entity.

7. The method of claim 1 , wherein the external code data type representation is a Core Components Technical Specification (CCTS) based representation.

8. The method of claim 1 , wherein the mapping is performed by serialization.

9. The method of claim 1 , wherein the internal code data type representation unique identifier provides a unique prefix associated with the developer the internal code data type representation further identifying a system type code, the system type code identified using the unique identifier.

10. The method of claim 9 , wherein the internal code data type representation also includes a transport object identifier, the transport object identifier including the unique prefix and a customer identifier.

11. The method of claim 1 , wherein the internal code data type representation further comprises a client specific switch value, the client specific switch value facilitating a client specific filtering of code values.

12. A system for providing code list extensibility, the system comprising:

a memory for storing instructions; and

at least one hardware processor operable to execute instructions stored on the memory to:

provide an external representation of a code data type, the external code data type representation having at least one external code value generated by a developer of at least one of a business object or a software suite for an existing business application and used by customers or software vendors,

provide an internal representation of the code data type, the internal data type representation having a second code value representation for the at least one internal code value, the internal code value representation including a unique identifier for the developer and is used by a database for the business application; and

map the external code data type representation and the internal code data type representation based at least in part on the unique identifier for the developer.

13. The system of claim 12 , wherein the internal code data type representation accommodates an ABAP namespace.

14. The system of claim 13 , wherein the unique identifier associated with the code value issuing entity is an ABAP namespace prefix.

15. The system of claim 12 , wherein the internal unique identifier is a first unique identifier associated with a first software program associated with the developer.

16. The system of claim 15 , further comprising a second unique identifier associated with a second software program associated with the developer.

17. The system of claim 12 , wherein the external code data type representation further comprises an agency identifier, the agency identifier identifying the code value issuing entity.

18. The system of claim 12 , wherein the external code data type representation is a CCTS based representation.

19. The system of claim 12 , the system further operable to receive a registration from the developer to establish the unique identifier.
