Question Re: Dynamic URL Smartforms in Technology Q&A

Dynamic URL Smartforms

Former Member — Fri, 27 May 2011 20:40:07 GMT

Hi all,

I've to insert a DYNAMIC url in a Smartform behind a label.

Some topics to consider:

- The Url is created in running time.

- The Smartform is called by a Standard Program, so, I can not change the Impressor Program.

- I want the url behind the word "LINK"

For example:

CONCATENATE: 'www.' sy-mandt 'sap' sy-datum '.com' into lv_url.

so I want insert it behind a text "LINK"

When SAP sends the form by email the user could click on "LINK" and go to the url before created.

Thanks a lot

Regards

Rodrigo

We have discussed this before here. For a modified anchor tag in a smartform, you need a callback function with a CHANGING parameter called DATA with type TTXCTOKEN. The name of the function is specified in the output_options-urlcall field in the smartform interface.

Thanks Brad, but could you explain me step by step?

I had read a lot of topics but there is not a solution for this.

My url is bigger than 42 characters

If you can, give me more details please.

Regards

Rodrigo.

Hi Rodrigo,

As Brad Bohn said, you have to search the forum. I did, with STXCTOKEN, and I got the answer. I don't understand why you are talking about a limitation of 42 characters, which does not exist.

Sandra,

In some topics in the forum said that when the length is less than 42 you can use some Function Modules:

Could you explain me How did you do? or maybe tell me where the solution is.

Thanks a lot

Hi Rodrigo,

sorry I have forgotten to say that I did see where you found this 42 characters "tale" (well maybe it was true on a past version), and I had updated that thread (the one you mention -> )

There's no limit that I've hit, though I haven't gone over 255 yet...

A simple example of the function callback code:


  DATA: ls_data TYPE LINE OF ttxctoken.

  LOOP AT data INTO ls_data.

    IF ls_data-string CS 'www'.

      IF ls_data-code EQ 'ST'.

        ls_data-string = text-h01.
        ls_data-len    = STRLEN( ls_data-string ).

      ELSEIF ls_data-code EQ 'LK'.

      ENDIF.

    ELSEIF ls_data-string CS 'mailto'.

      IF ls_data-code EQ 'ST'.

        ls_data-string = text-m01.
        ls_data-len    = STRLEN( ls_data-string ).

      ELSEIF ls_data-code EQ 'LK'.

      ENDIF.

    ENDIF.

    MODIFY data FROM ls_data.

  ENDLOOP.

Hi All,

Thanks a lot!

I'm going to implement it as you said. If I need some help I will tell you.

Give me a couple of hours

Hi All,

I have to fill this field ls_output-urlcall. But as I said before, I can not change anything before the form is called. Because It's a standard program, NO exit, NO badi, nothing.

Thanks

I really need your help! please...

Hi All,

You said before "We have discussed this before here." but there isn't a solution.

Could you tell me more details, step by step PLEASE!!

It isn't helpful to me "go throw the forum" because I did it.

Thanks

Well, there's no choice, I think limit is around 66 characters for the URL without the "urlcall" callback function module. If you want more characters, use the callback, this is a very little modification of the standard (I don't really see the danger of doing so). Propose the 2 solutions to the client, he'll decide. By the way, why wouldn't you create a tiny URL with redirection?

Sandra,

Ok, let's supose that the URL lenght is less than 66 char. For example www.yahoo.com

The steps are:

1) Create an Element Text in the Smartform called LOGIN with the text "LOGIN"

2) Create a Program Lines Element with the following code:

HERE, HOW SHOULD I USE THE FUNCTION MODULE "HR_RCF_SF_URL_CALLBACK"?

Brad, post this example: but How I should fill the data table??!!

DATA: ls_data TYPE LINE OF ttxctoken.

LOOP AT data INTO ls_data.

IF ls_data-string CS 'www'.

IF ls_data-code EQ 'ST'.

ls_data-string = text-h01.

ls_data-len = STRLEN( ls_data-string ).

ELSEIF ls_data-code EQ 'LK'.

ENDIF.

ELSEIF ls_data-string CS 'mailto'.

IF ls_data-code EQ 'ST'.

ls_data-string = text-m01.

ls_data-len = STRLEN( ls_data-string ).

ELSEIF ls_data-code EQ 'LK'.

ENDIF.

MODIFY data FROM ls_data.

ENDLOOP.

Then I guess that the match is automatic.

Thanks

Rodrigo

Brad, post this example: but How I should fill the data table??!!

You don't - SAP does. The only thing you need to specify is the function name in the call and then write the function code...

BTW, I should mention that in my simple example, I had text elements - the text in those elements is the 'friendly text' only, not any url identifiers. I agree with Sandra - the enhancement (or replacement of the standard program via config) is trivial...

Re: Dynamic URL Smartforms

Former Member — Tue, 31 May 2011 20:40:56 GMT

Thanks Brad.

So, If I can not change the standard program which made the Smartform call, I can not implement the dynamic URL, is this correct?

Thanks again

Regards

Rodrigo

Re: Dynamic URL Smartforms

brad_bohn — Tue, 31 May 2011 20:55:04 GMT

Correct, because that's the only option SAP provides for 'friendly' url's with smartform-based PDF's that I'm aware of. You may want to consider an implicit enhancement if you can...

In fact, you could use <%W>http://www.yahoo.com< / > (omit the spaces). The callback function module is not required if we let hyperlink text = URL

As I said before the URL is DYNAMIC!! www.yahoo.com.ar is just an example!

Re: Dynamic URL Smartforms

Sandra_Rossi — Tue, 31 May 2011 21:22:21 GMT

Okay, forget my remark about not using the callback function module... But you MUST define an hyperlink (%W) so that SAP calls the callback function for it. So, for a dynamic URL, you'll have to change it dynamically OF COURSE using the function module.

People,

I found the solution for this problem, give me a while and then I'll explain it step by step (the best way to answer a question, not just examples or links)

When some people make a question, please try to be nice and give us more details
