how to comapre text lines?

[Former Member]

I have an input window which gets the texts from a file initially.

After reviewing the details, user can change some parts of the text.

Now the task is to identify the changes while downloading the same.

How to achive the part of identifying the changes?

(I did a read for the whole line but it does not tell me which word has been changed.)

Thanks,

Ven

did you try using the FM : SF_STRING_CHECK

If your table has 72 characters, than you can use the FM MAKE_TEXT_DELTA

How do you use the above function modules for text comparison?

MAKE_TEXT_DELTA - returns the latest entered value

while sf_string_check - what should be the inputs?

I checked the code.. of the FM yesterday... it returns the string with is different... I guess that is not what you are looking for..

Input:

How r u?

how r u here?

result :
how r u here?

Youa re right J@y.

Here is what I am trying to do:

In the ALV clikc on a button and int he resultant window, enter some text and save it.

Click on the sam button, open the window with the previously saved text.

Now change some sentences and SAVE - it should highlight the changes.
