The reason we cannot use the READ_TEXT function in an ABAP mapping is twofold:
It requires table parameters - which cannot be used in ABAP dataflows
It does raise exceptions if no data is found - a condition which would be okay for us
Therefore the solution could be to write a new SAP function module using the READ_TEXT function inside but doing exactly what we want it to do.

FUNCTION Z_AW_READ_TEXT_ALL.
*"----------------------------------------------------------------------
*"*"Local Interface:
*"  IMPORTING
*"     REFERENCE(ID) TYPE  THEAD-TDID
*"     REFERENCE(LANGUAGE) TYPE  THEAD-TDSPRAS
*"     REFERENCE(NAME) TYPE  THEAD-TDNAME
*"     REFERENCE(OBJECT) TYPE  THEAD-TDOBJECT
*"  EXPORTING
*"     REFERENCE(TEXT) TYPE  CHAR2000
*"----------------------------------------------------------------------
DATA BEGIN OF TEXTHEADER.
        INCLUDE STRUCTURE THEAD.
DATA END OF TEXTHEADER.
DATA BEGIN OF TEXTLINES OCCURS 10.
        INCLUDE STRUCTURE TLINE.
DATA END OF TEXTLINES.
CLEAR TEXTHEADER.
data: l_name type TDOBNAME."TR
l_name = name."TR
CALL FUNCTION 'READ_TEXT'
       EXPORTING
            OBJECT                  = OBJECT
            ID                      = ID
            LANGUAGE                = LANGUAGE
            NAME                    = l_NAME "TR
       IMPORTING
            HEADER                  = TEXTHEADER
       TABLES
            LINES                   = TEXTLINES
       EXCEPTIONS
            ID                      = 1
            LANGUAGE                = 2
            NAME                    = 3
            NOT_FOUND               = 4
            OBJECT                  = 5
            REFERENCE_CHECK         = 6
            WRONG_ACCESS_TO_ARCHIVE = 7
            OTHERS                  = 8.
LOOP AT TEXTLINES.
   CONCATENATE TEXT TEXTLINES into TEXT SEPARATED BY space.
ENDLOOP.
ENDFUNCTION.

This function does not have any exceptions by itself, so even if the READ_TEXT function does raise one, it will finish successfully and return an empty text.
