Use of FM Read_Text

 In SAP we use Function Module to get the desire value maintaining different parameters.

Usually we need to call FM when value directly not in a table. In FM we need to pass ID, Object, Name.

Here ID mean where from it reads. Object : which object of text to be read. Name : Which name f text to be read. In below I share a demo code with you.Suppose here name = Client number +Inspection Lot Number+L, so we need to concatenate both of them and keep them in a variable.

DATA: CON LIKE THEAD-TDNAME .
DATA: CON1 TYPE STRING .
L_D = 'L'. 

CONCATENATE SY-MANDT WA-PRUEFLOS INTO CON1.
CONCATENATE CON1 L_D INTO CON.

DATA: I_LINE TYPE STANDARD TABLE OF TLINE,
        W_LINE LIKE LINE OF I_LINE.


  CALL FUNCTION 'READ_TEXT'
    EXPORTING
      CLIENT                  = SY-MANDT
      ID                      = 'QAVE'
      LANGUAGE                = 'E'
      NAME                    = CON
      OBJECT                  = 'QPRUEFLOS'
*     ARCHIVE_HANDLE          = 0
*     LOCAL_CAT               = ' '
* IMPORTING
*     HEADER                  =
*     OLD_LINE_COUNTER        =
    TABLES
      LINES                   = I_LINE
    EXCEPTIONS
      ID                      = 1
      LANGUAGE                = 2
      NAME                    = 3
      NOT_FOUND               = 4
      OBJECT                  = 5
      REFERENCE_CHECK         = 6
      WRONG_ACCESS_TO_ARCHIVE = 7
      OTHERS                  = 8.

 
  IF SY-SUBRC <> 0.
* Implement suitable error handling here
  ENDIF.

After getting  values we need to loop it and pass the internal table.
