ABAP Select data from SAP table EDOC_PT_INV_MAPPING_SOURCE into internal table

Below is a number of ABAP code snippets to demonstrate how to select data from SAP EDOC_PT_INV_MAPPING_SOURCE 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 EDOC_PT_INV_MAPPING_SOURCE.

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 EDOC_PT_INV_MAPPING_SOURCE 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.

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

*Select data and declare internal table using  in-line method @DATA 
SELECT *

  INTO TABLE @DATA(IT_EDOC_PT_INV_MAPPING_SOURCE2).

*You can also declare the header/work area using the  in-line DATA declaration method 
READ TABLE IT_EDOC_PT_INV_MAPPING_SOURCE INDEX 1 INTO DATA(WA_EDOC_PT_INV_MAPPING_SOURCE2).


*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 EDOC_PT_INV_MAPPING_SOURCE
