Hi,

Are you completing the PO number with zeroes? Just in case...

I've used this code succesfully to show PO item text in sapscript form:

code

CONSTANTS: c_tdid LIKE thead-tdid VALUE 'F01', " Texto de posicion

c_tdobject LIKE thead-tdobject VALUE 'EKPO'. " Objeto de texto OC

CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT' " Se agregan ceros al nro. de OC

EXPORTING

input = l_ebeln

IMPORTING

output = l_ebeln.

CONCATENATE l_ebeln l_ebelp INTO l_tdname. " Se adapta l_tdname al formato del NAME para las OC

REFRESH i_lineas.

CALL FUNCTION 'READ_TEXT' " Esta funcion lee el texto de posicion

EXPORTING

client = sy-mandt

id = c_tdid

language = sy-langu

name = l_tdname

object = c_tdobject

TABLES

lines = i_lineas

EXCEPTIONS

id = 1

language = 2

name = 3

not_found = 4

object = 5

reference_check = 6

wrong_access_to_archive = 7

OTHERS = 8.[/code]

Regards,

Kumar

Hi Raja,

Just put a break-point in this Fm and see how the transaction ME23N is reading it, I mean which all details are passed to get back the long text.

Atish

Hi,

Check the following code

CONSTANTS: c_tdid LIKE thead-tdid VALUE 'F01',

c_tdobject LIKE thead-tdobject VALUE 'EKPO'.

CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'

EXPORTING

input = l_ebeln

IMPORTING

output = l_ebeln.

CONCATENATE l_ebeln l_ebelp INTO l_tdname.

REFRESH i_lineas.

CALL FUNCTION 'READ_TEXT'

EXPORTING

client = sy-mandt

id = c_tdid

language = sy-langu

name = l_tdname

object = c_tdobject

TABLES

lines = i_lineas

EXCEPTIONS

id = 1

language = 2

name = 3

not_found = 4

object = 5

reference_check = 6

wrong_access_to_archive = 7

OTHERS = 8.[/code]

Hi Raja,

READ_TEXT* provides a text for the application program in the specified work areas.

The function module reads the desired text from the text file, the text memory, or the archive. You must fully specify the text using OBJECT, NAME, ID, and LANGUAGE. An internal work area can hold only one text; therefore, generic specifications are not allowed with these options.

After successful reading, the system places header information and text lines into the work areas specified with HEADER and LINES.

If a reference text is used, SAPscript automatically processes the reference chain and provides the text lines found in the text at the end of the chain. If an error occurs, the system leaves the function module and triggers the exception REFERENCE_CHECK.

Function call:

CALL FUNCTION 'READ_TEXT'

EXPORTING CLIENT = SY-MANDT

OBJECT = ?...

NAME = ?...

ID = ?...

LANGUAGE = ?...

ARCHIVE_HANDLE = 0

IMPORTING HEADER =

TABLES LINES = ?...

EXCEPTIONS ID =

LANGUAGE =

NAME =

NOT_FOUND =

OBJECT =

REFERENCE_CHECK =

WRONG_ACCESS_TO_ARCHIVE =

Export parameters:

CLIENT

Specify the client under which the text is stored. If you omit this parameter, the system uses the current client as default.

Reference field: SY-MANDT

Default value: SY-MANDT

OBJECT

Enter the name of the text object to which the text is allocated. Table TTXOB contains the valid objects.

Reference field: THEAD-TDOBJECT

NAME

Enter the name of the text module. The name may be up to 70 characters long. Its internal structure depends on the text object used.

Reference field: THEAD-TDNAME

Enter the text ID of the text module. Table TTXID contains the valid text IDs, depending on the text object.

Reference field: THEAD-TDID

LANGUAGE

Enter the language key of the text module. The system accepts only languages that are defined in table T002.

Reference field: THEAD-TDSPRAS

ARCHIVE_HANDLE

If you want to read the text from the archive, you must enter a handle here. The system uses it to access the archive. You can create the handle using the function module ACHIVE_OPEN_FOR_READ.

The value '0' indicates that you do not want to read the text from the archive.

Reference field: SY-TABIX

Default value: 0

Import parameters:

HEADER

If the system finds the desired text, it returns the text header in this parameter.

Structure: THEAD

Table parameters:

LINES

The table contains all text lines that belong to the text read.

Structure: TLINE

Exceptions:

The text ID specified in the parameter ID does not exist in table TTXID. It must be defined there together with the object of the text module.

LANGUAGE

The parameter LANGUAGE contains a language key that does not exist in table T002.

NAME

The parameter NAME contains the name of a text module that does not correspond to the SAPscript conventions.

Possible errors:

The field contains only blanks.

The field contains the invalid characters ‘*’ or ‘,’.

OBJECT

The parameter OBJECT contains the name of a text object that does not exist in table TTXOB.

NOT_FOUND

The system did not find the specified text module.

REFERENCE_CHECK

The text module to be read has no text lines of its own but refers to the lines of another text module. This reference chain can include several levels. For the current text, the chain is interrupted, that is, one of the text modules referred to in the chain no longer exists.

WRONG_ACCESS_ TO_ARCHIVE

The exception WRONG_ACCESS_TO_ARCHIVE is triggered if an archive is accessed using an incorrect or non-existing archive handle or an incorrect mode (that is, read if the archive is open for writing or vice versa).

IF found Helpfull Do reward.

Regards.

Eshwar.
