How to read text with READ_TEXT FM

Most of text in SAP are stored in STXH and STXL tables.
We can read text by read_text fm. If you can not find input parameters of the fm , you can use STXH tables.

Example  :

Read text purchase requisition header note

 T-code : ME52N (Change Purchase Req.)

 

Find READ_TEXT import parameters :

CLIENT  = SY-MANDT
ID  = ?
LANGUAGE = sy-langu
NAME  = ?
OBJECT  = ?

Now go to SE16N and look for the table STXH , give your key parameter( banfn – purchasing req. number) into TDNAME field.

ID  = ‘B01’
NAME  = ‘5000000112’
OBJECT  = ‘EBANH’

Now we have all import parameter to call read_text.( If you don’t want to call the read_text , use the table STXL for getting text lines.)

CODES :

BREAK xasag.
DATA : lv_name type THEAD-TDNAME,
gt_lines type table of tline,
gs_line type tline.

lv_name = '50000000112'.
CALL FUNCTION 'READ_TEXT'
EXPORTING
CLIENT = SY-MANDT
id = 'B01'

EXCEPTIONS

NOT_FOUND = 4
OBJECT = 5

OTHERS = 8
.
IF sy-subrc <> 0.
* Implement suitable error handling here
ENDIF.

loop at gs_lines into gs_line.
*gs_line-tdline.

endloop.

You can see header note rows in the debug mode.
