Below is a number of ABAP code snippets to demonstrate how to select data from SAP V001ICDUNNING table and store it within an internal table, including using the newer @DATA inline declaration methods. It also shows you various ways to process this data using ABAP work area, inline declaration or field symbols including executing all the relevant CONVERSION_EXIT routines specific to V001ICDUNNING.

Sometimes data within SAP is stored within the database table in a different format to what it is displayed to the user. These input/output conversation FM routines are what translates the data between the two formats.

There is also a full declaration of the V001ICDUNNING table where each field has a char/string type for you to simply copy and paste. This allows you to use processing that is only available to these field types such as the CONCATENATE statement.

DATA: IT_V001ICDUNNING TYPE STANDARD TABLE OF V001ICDUNNING,
      WA_V001ICDUNNING TYPE V001ICDUNNING,

*Original SAP ECC Select statement 
SELECT *
*restrict ABAP select to first 10 rows
 UP TO 10 ROWS      
  FROM V001ICDUNNING
  INTO TABLE IT_V001ICDUNNING.

*Select data and declare internal table using  in-line method @DATA 
SELECT *
  FROM V001ICDUNNING
  INTO TABLE @DATA(IT_V001ICDUNNING2).

*You can also declare the header/work area using the  in-line DATA declaration method 
READ TABLE IT_V001ICDUNNING INDEX 1 INTO DATA(WA_V001ICDUNNING2).


*Latest ABAP cloud SELECT statement using the FIELDS syntax. But note to following the clean core principles you should not select directly from an SAP table 
* and should instead use a CDS view or create you own CDS and use that.
SELECT FROM V001ICDUNNING
  FIELDS *
*  WHERE would go here
  INTO TABLE @DATA(IT_V001ICDUNNING2).
