ABAP by Ajay

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.   ****************************...

  Data Model is design of Data. How related data is put together in data collection called Entities and how entities relate to each other. Entity Types     *  Entity Type or Entity is like a structure which can hold one data record. In ABAP programming terms, we can compare it to a work area.     *  Entity type has properties with some of the properties marked as Keys. More details on the properties like Type, Length are also defined. Entity Sets     *  Entity Sets are collection of same entity types. Order Detail is an entity – Order details i.e. Collection of multiple order detail entities is an Entity Set. This is like a table.     *  Entity Set simply refers to Entity Type. Association     *  Associations are relationships between two entity types. It defines the cardinality/multiplicity between the related entities.     *  In this example, Orders and Order Details Entity Sets ar...

    *  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 ...

       * AMDP -- ABAP managed database procedures.     * It is a framework for managing and calling stored/database procedure and database function in as ABAP.      * The AMDP manages AMDP procedures and functions. ------------------------------------------------------------------------------------------------------------------------------     * AMDP is a global class that contains special tag interface that starts with IF_AMDP_MARKER_*.     * For HANA database  IF_AMDP_MARKER_HDB. -------------------------------------------------------------------------------------------------------------------------------     * Constructors can't be implemented as AMDP methods.     * There are two types of AMDP methods.               1. AMDP procedure implementation.               2. AMDP function implementation.      1...

      * There are 4 classes used to send adobe form as an email.               1.  CL_BCS: It is used for creating the sending request, sending the document, adding the recipient etc.               2.   CL_DOCUMENT_BCS: It is used to create the document and adding attachment etc.               3.  CL_SAPUSER_BCS: It is used to create SAP users.               4.   CL_CAM_ADDRESS_BCS: It is used to create external recipients.       * There are various step to send adobe form as email.                         1. Get the PDF content of adobe form.                         2. Convert the PDF from rawstring to binary format.  ...

          ABAP dictionary-based  interface.               * This interface has different standard parameters in the form interface.          XML schema-based interface.               * We use this interface type if we create forms in form builder in web Dynpro for abap.          Smartform compatible Interface.               * This interface also has different standard parameters in the form interface. ************************** * ** Thank You ********************** ** **

  Adobe forms.      * Adobe forms are interactive smart forms.      * We can interact with the output of adobe forms.      * Adobe forms provide the output in the form of PDF.      * T code - SFP.      * In adobe forms we need to create an interface the same interface can be used in multiple adobe forms.     * Adobe form also generates a function module at run time.     * Adobe LiveCycle designer is required to design a layout with the help of adobe form. Diff between SF & AF.      * Smart forms are not interactive forms whereas adobe forms are interactive Smart forms.      *   > In smart forms the form interface, global definition, pages, windows are all together           > In adobe forms the form interface, global definitions are the part of  interface and layou...
