Finding Attached document URL

Question

I'd like to find URL of attached document in CRM .
So I  found the URL using the class cl_crm_documents=>get_with_url  .
But URL Information had a problem.
For example,
this is the URL of attached document.
http://xxx/sap/bc/contentserver/300?get&pVersion=0046&
contRep=CRMORDER&
docId=40F9B6CE0CB4AF41BE10CE3CE0A30F70&
compId=%25EC%25A0%259C%25ED%2592%2588%25EA%25B2%2580%25EC%2588%2598.ppt&
accessMode=r&
authId=CN%3DRDV&
expiration=20100618103631&secKey=xxxxx
The problem is expiration .
When I executed  class cl_crm_documents=>get_with_url  , this expiration is updated with executed day.
If I  obtained that URL , today I can't use .
Because expiration was passed.
Can I solve this problem ?
Is there another method that finding URL of attatched documents ?
Please, help me ^^;;

Answer 1

Ok i know this thread is older but i have / had the same problem.
So there are two questions:
1.) How to access a document via a url which validy is expired.
2.) How to access a docmument via a url longer than 255 chars for macro porcessing.
Solution to Question 1: You can simply regenerate a url with a new expiration date, this works fine with the folliwing coding:
* Get URL
  cl_crm_documents=>get_with_url(
    exporting
      loio     = is_loio
      phio     = is_phio
      url_type = crmkw_url-standard
    importing
      url      = lv_uri
    exceptions
      no_io    = 1
      others   = 2
  if sy-subrc <> 0.
    return.
  endif.
* Calculate expiration time
lv_expiration = cl_abap_tstmp=>add( tstmp   = mv_now
                                            secs    = lv_exp_in_sec ).
* Regenerate Link with new expiration time
call function 'SCMS_URL_REGENERATE'
      exporting
        absolute_uri    = lv_uri
        expiration      = lv_expiration
      importing
        http_uri        = lv_uri_http
        https_uri       = lv_uri_https
      exceptions
        error_parameter = 1
        others          = 2.
Question 2:
I am facing the same problem at the moment but i have no solution....
I want to access a document for an excel macro processing by:
* open existing file
   call method of lr_excel 'Workbooks' = lr_workbooks.
   call method of lr_workbooks 'OPEN'
     exporting
       #1 = lv_uri_http.
But I am not able to open this document. If I copy the URL to the browser it works fine and I can access the document. I guess the problem is that the URL is longer than 255 chars. Did you found any solution for this problem yet? or a alternative way acccessing documents in the kw for a macro processing?
Thanks a lot!
