When defining an ABAP Managed Database Procedure (AMDP), which actions must be taken?

When defining an ABAP Managed Database Procedure (AMDP), it is essential to specify the database system and the programming language used for the implementation. This is crucial because AMDP allows developers to write database-specific logic using SQLScript or similar languages that are specific to the database used, such as SAP HANA.

Specifying the database system ensures that the database procedures are optimized for the particular database technology being utilized. It also informs the system about which SQL dialect to expect, which is key to the correct execution of the procedure.

While marking the AMDP method as READ-ONLY is relevant for certain use cases, it is not a mandatory action for all procedures. Similarly, defining all parameters to be passed by value is not inherently required, as parameters can also be passed by reference based on specific needs. Listing ABAP Dictionary tables in the USING clause is necessary for accessing those tables within the procedure body, but this is a separate step that can vary depending on whether or not those tables are needed.

The requirement to specify the database system and language is foundational for ensuring that AMDPs function correctly and leverage the capabilities of the database they are designed for.
