Add Text

[Former Member]

Hi,

The requirement I'm working with requires to add text to the existing text object. I used READ_TEXT to read the existing text and SAVE_TEXT to append the additional text. There is a scenario where there might be no text in the text object. In this case the FM READ_TEXT fails and the program stops at that point. Is there any way we can check if there is already some text in a text object so that only in that case we can use FM READ_TEXT else we just use SAVE_TEXT to append new text.

Any help will be appreciated.

Thanks,

ALAM.

Read data from STXH. if no record then use SAVE_TEXT.

Hi Muthappan,

Do you mean to say if there exists an entry in STXH then only use READ_TEXT?

To check if there is a text exist, you have to use READ_TEXT.

You can jus go without checking sy-subrc or your itab is initial after the READ_TEXT stmt, let the code pass through both the FM all the time you run.

Hello Senthil,

Do you mean if there is no text the READ_TEXT FM goes for a Short dump?? - It does not dump but it stops at an error message inside the READ_TEXT FM.

Hi Alam,

to check if the text exists just use FM READ_TEXT. If there is no text, the FM will raise exception NOT_FOUND which you catch via subrc code.

So it is just enough to use case of subrc after call of the FM.

If subrc is 0 then text exists, then just edit table with text and use SAVE_TEXT.

If text doesn't exitst - I don't know which value of subrc is it now (you will get it when you use pattern button) then first call INIT_TEXT and then SAVE_TEXT (or you can use CREATE_TEXT - but this is not working properly in some cases because of COMMIT inside the body).

Regards,

Karol

You have to include the exception NOT_FOUND in your call to FM READ_TEXT. Then you will be able to check sy-subrc.
