Problems with text with more than 250 characters using smartforms

Hi, In this moment i have a problem:

I use a text element to display one text, but this text has more than 250 characters.

I use a code to put this text in this field and i check this field and i can see all text but in the screen this text is not complete.

The code that i use is :

CALL FUNCTION 'READ_TEXT'

EXPORTING

client = SY-MANDT

id = 'IVER'

language = 'S'

name = aux_obj

object = 'MATERIAL'

TABLES

LINES = ti_textos

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.

loop at ti_textos.

concatenate zdesc_largop ti_textos-tdline into zdesc_largop

separated by ' '.

endloop.

ENDIF.

thanks for the help

Henry
