Introduction to ODATA in SAP.


    * OData is an open standard that is both a data format and a protocol for consuming and manipulating data in a uniform way.

    * OData is the way of communication between frontend which is SAP UI5/FIORI and SAP backend.

    * SAP Gateway component handles the OData Services. The Gateway component can be either embedded in ECC/S4 HANA or it can be on a separate gateway system.

    * Each OData service is represented by a URI (Uniform Resource Identifier) or URL (Uniform Resource Locator). We will use URI term going forward.

    * OData Service has two types of documents – Service and Metadata.

    * Atom format (xml) and JSON formats are supported.

    * Any web browser can be used to explore OData Service.

    *  Metadata

            - Metadata contains information about all the components of the data model for OData Service such as

            - Entity type name, properties, keys, and navigation properties

                 - Association name, principal and dependent entities.

                   -  Entity Sets

                - Association Sets

New syntax for append- VALUE (new syntax 7.4+) in ABAP

Image
* We use APPEND statement to insert the records at the last of the internal table. * In SAP ABAP new syntax, we can use VALUE expression instead of APPEND statement. * Value expression is a powerful mechanism to declare as well as initialize the internal tables. * It is a powerful utility where we can achieve the result with minimal coding. * Value expression is of 2 types.      -  Define the type before using it with VALUE keyword. The type defined is structure type  or table type.      -  Using # character for type and use it with VALUE keyword. Report REPORT  zab_rp_append_value . TYPES :  BEGIN  OF  ls_stu ,          st_id ( 10 )    TYPE  n ,          st_name ( 15 )  TYPE  c ,         END  OF  ls_stu . DATA :  lt_stu  TYPE  TABLE...

Read statement new syntax in ABAP. (7.4+).

Image
*  Before ABAP 7.4, we used READ TABLE statement to read the first matching record from the internal table  based upon key or index . * In SAP ABAP new syntax, instead of READ TABLE , we can use the table expressions. * We need to use the square bracket [ ], In the square bracket, we need to specify the key or index. * While using table expression, If the table entry does not exist, system throws the exception CX_SY_ITAB_LINE_NOT_FOUND. * Use line_exists statement to check the existence of a record. Report REPORT  zab_rp_read_new . TABLES :   vbak . SELECT-OPTIONS :   s_vbeln  FOR  vbak - vbeln . SELECT  vbeln , erdat , erzet , ernam , auart         FROM  vbak         INTO  TABLE  @DATA ( lt_vbak )          WHERE  vbeln  IN  @s_vbeln . WRITE :   'Index value'  COLOR  5 . READ  T...
