What is the difference between AMDP procedure and CDS view
AMDP is used to work with stored procedures that further go to the HANA DB layer and execute that, whereas CDS views can be created to read and process data at the database level while AMDP can be created to process and modify data at the database level.May 19, 2019
What is AMDP in Hana ABAP
Since ABAP-Managed Database Procedures are implemented as methods of a global ABAP class, the editing environment for AMDP is the ABAP class editor. ABAP-Managed Database Procedures is one of the recommended patterns for use in ABAP code optimization within the context of ABAP development on SAP HANA.
How many types of AMDP method exists
There are two different kinds of AMDP methods: those that define AMDP procedures without a return code and those that define AMDP functions with a return code.
What is the syntax for implementing AMDP method
The syntax used to specify an AMDP procedure or function is class=>meth, where class denotes the name of the procedures AMDP class and meth denotes the name of the procedures or functions AMDP implementation.
What is the use of table function in CDS
Each CDS table function includes the following elements: The actual CDS entity of the table function that is generated in the ABAP Dictionary. A CDS table function is defined using the ABAP CDS statement DEFINE TABLE FUNCTION. A CDS table function can be used as the data source in Open SQL read statements.
What are table functions in SAP HANA
You can use the from clause of a SQL statement to call a table function. Table functions are functions that users can query like any other database tables, and you can add them as a data source in your graphical calculation views.
How do I set up an external view in Hana
Step 1: Create HANA Attribute view :
- Step 2: Save and Activate the view and check the data by using 'Data Preview' option.
- Step 1: Go to 'ABAP' prospective.
- Step 2: To create this external view under an ABAP package, perform a right-click.
- Step 3: Expand 'Dictionary' folder and click on 'Dictionary View'.
Is client specific and restricts access to a client the calling AMDP method
The calling AMDP method AMDP_METHOD must also permit this restriction. In the following code line ABAP developers can see how I called CDS view within AMDP and applied a WHERE clause using APPLY_FILTER command. Z_CDS_VIEW is client-specific and restricts access to a client.
Can we use CDS view in AMDP
To take advantage of the performance of HANA and the features of ABAP, we can use CDS views inside of ABAP programs with AMDP. CDS also offers feature-rich annotations, which allow us to expose CDS views as oData sources in a few easy steps.
What is AMDP procedure
What is AMDP? AMDP, or ABAP Managed Database Procedures, is a type of procedure. Inside AMDP, code can be written using SQLSCRIPT, a scripting language that is similar to SQL and is simple to understand.
What are the different types of CDS views
There are two types of CDS views: ABAP CDS views and HANA CDS views.
What are the advantages of AMDP
Complex calculations involving multiple independent steps/processes can be completed using an AMDP method, which is simple to implement in ABAP and can take advantage of powerful native SQL features like currency conversion and CE functions.May 31, 2016
What is the difference between HANA CDS and ABAP CDS
HANA CDS views aim to support the development of native SAP HANA applications, whereas ABAP CDS views are database independent.Jun 3, 2021 The CDS objects created using HANA CDS are not controlled by ABAP dictionary and therefore cannot be consumed in ABAP Programs or Open SQL.
What is the advantage of CDS view
The benefits of CDS Views include support for the GROUP BY, WHERE, HAVING, and UNION clauses, as well as full, cross, inner, outer, and right outer joins, as well as aggregation and numeric functions, as well as automatic client handling.
Where do we use AMDP
An AMDP is a piece of code that is executed in the SAP HANA layer. The data it fetches includes some business logic that will be performed on the fetched data, typically on enormous amounts of data.
What is AMDP class in SAP HANA
A global class in the class library is referred to as an AMDP class if it includes one or more of the tag interfaces listed below, such as IF_AMDP_MARKER_HDB for the SAP HANA database.
What is AMDP script
SQL Script is a script language that is used to program SQLScript procedures and SQLScript functions in the SAP HANA database and is described in the SAP HANA SQLScript Reference.
What is the use of IF_AMDP_MARKER_HDB
Marker Interface for DB Procedures is IF_AMDP_MARKER_HDB.
