DATABASE FUNCTION is used in place of ABAP-Managed Database Procedures (AMDP) are a method of executing database-specific procedures or functions directly from ABAP code, but in a way that is tightly When we use openSQL, filtering data from parameters and select-option is too easy. CDS table functions can only be used in a database system that supports AMDP. Types of AMDP- AMDP Procedures, AMDP Functions Interface for AMDP is IF_AMDP_MARKER_HDB. As such, they support the HANA platform code pushdown An AMDP class can only be edited in ADT (Eclipse). Instead, it is a column of the tabular return value of the associated AMDP function implementation and also a regular component of the structured data type represented by the CDS entity. CDS scalar functions are available in CDS view entities in operand positions that expect scalar values, similar to built-in functions. Additionally, AMDP is only a method, so if we have more AMDP methods, how can we call another AMDP inside the AMDP method? Stay tuned!!! We will learn it in this article. . ABAP-Managed Database Procedures (AMDP) are a method of executing database-specific procedures or functions directly from ABAP code, but in a way that is tightly AMDP is a class that allows us to write the Object Oriented classes at back-end for the views mentioned above. 1. This example accesses AMDP functions that are declared and implemented in the AMDP class CL_DEMO_AMDP_FUNCTIONS_CS. Does AMDP function implementations support exception handling? No exceptions can be declared for AMDP function implementations. via double click on the left From now on, you can now also debug CDS table functions using the AMDP debugger. 50, AMDP supports also database functions with a tabular return value. CLASS-METHODS meth FOR TABLE FUNCTION cds_entity. If a query calls an AMDP scalar function more than once with the same values for the input parameters and with the option DETERMINISTIC, the function is AMDP Function Method with sqlscript AMDP Procedure method and AMDP function method .
