Introduction to RAP & CAP in SAP

RAP (ABAP RESTful Application Programming Model):

  • It's SAP's modern way for ABAP developers to build business applications.  
  • It helps create applications that work well in the cloud and with SAP S/4HANA.  
  • It uses standard web technology (called REST) to communicate.  
  • Think of it as an upgrade to how ABAP applications are built.

CAP (SAP Cloud Application Programming Model):

  • It's another way SAP helps developers build applications, but it's more focused on cloud-based development.
  • It's not limited to the ABAP language; you can use others like JavaScript and Java.  
  • It's designed to make it easier to connect to different services and databases in the cloud.  
  • Think of it as a more general toolkit for building cloud applications.

Main Simple Difference:

  • RAP is mainly for modernizing ABAP development within the SAP ecosystem.
  • CAP is a broader model for building cloud applications using various technologies.

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...
