Hello, ๐๐๐ ๐๐จ๐ฆ๐ฆ๐ฎ๐ง๐ข๐ญ๐ฒ! When starting with your unmanaged RAP application, youโll need to implement all CRUD functionalities according to your business logic, as there is no automatic functionality provided. While implementing the create functionality, you may encounter errors due to the absence of UUID or unique ID creation. This can be avoided by using the early numbering method to generate UUIDs. To assist you in this process, Iโve put together a brief guide to support your development journey.
๐คLetโs explore this topic together! I invite you to share your thoughts and insights in the comments below.
What is Early numbering in RAP (RESTful Application Programming) ?
The numbering type early numbering refers to an early value assignment for the primary key field. In this case, the final key value is available in the transactional buffer instantly after the MODIFY request for CREATE. The key value can either be given by the consumer (externally) or by the framework (internally). In both cases, the newly created BO instance is clearly identifiable directly after the CREATE operation has been executed.

METHODS earlyNumbering_ Create method FOR NUMBERING [IMPORTING] entities FOR CREATE business _ object _ entity.
Step 1: Your behavior definition is unmanaged so every method and every operation need to be implemented and creating key fields is one of the functionality. for that use early numbering key word as below.
Note ๐ต๏ธโโ๏ธ: If their is association with other entity then โearlynumbering_cba_Academicโ or associated entity numbering will be created else will not generate.
Step 2: The implementation will require to use standard class for generating your UUID number and map that generated number for your key field.
โก๏ธA UUID is generated for the ID field using the cl_uuid_factory class, where create_system_uuid() creates the UUID and create_uuid_x16() formats it.
โก๏ธmapped-student using a VALUE constructor, filtering entities for those with an initial ID, and maps %cid, %is_draft, assigning the new UUID to id.
๐ The UUID number generation in debug mode for understanding the operation and assignment to mapped table.
Finally this created UUID number will appear for your Create unmanaged functionality.
