Replace Some Characters in the Middle of Text.

Requirement:

To replace the 5th character in a 10-character string (or any string), use the ABAP overlay statement or the replace section command. In ABAP, character offsets are zero-based, meaning the 5th character is at offset

Solution:

Here are the two best approaches for doing this:

Method 1: Using OVERLAY (Best for replacing specific offsets)

abap

DATA: gv_string TYPE string VALUE '1234567890'.

" The 5th character is at offset 4 (length 1). Replace it with 'X'
OVERLAY gv_string WITH '    X' ONLY ' '.

Method 2: Using REPLACE SECTION (Best for explicit length)

abap

DATA: gv_string TYPE string VALUE '1234567890'.

REPLACE SECTION OFFSET 4 LENGTH 1 OF gv_string WITH 'X'.

Method 3: Inline Expression (ABAP 7.40+)

abap

DATA(gv_string) = '1234567890'.

gv_string = |{ gv_string(4) }X{ gv_string+5 }|.

Output for all methods: 1234X67890

Upload Log Item Text to FI Document

Question:
I need to upload FI document posting using BAPI_ACC_DOCUMENT_POST. However item text that I received is too long and need to store at item long text. So can we use BAPI_ACC_DOCUMENT_POST to upload long text for item text? If this possible, may I know how to do this.

Answer: 
You cannot pass item long text using this BAPI, Call the function module SAVE_TEXT after successfull call of BAPI Call Save_Text with following parameters. Text_ID : 0001 (Notes) Text_object : DOC_ITEM (Line Item Text) Language : EN Text Name : Company code +Document NO + Fiscal Year + Line item ID

Function Example: READ_TEXT ABAP Wrapper Function

by Vicky Bolster

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.
The code I came up with is:

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.
