Extending GOS with Create Multiple Attachment


Intent of this blog post is provide a working prototype for additional GOS service to upload multiple attachment together in one go.

Business Requirement

Some time it is difficult for users to upload 7-8 documents in GOS using the option ‘Create Attachment’, as the same steps needs to be repeated several times. So users require a new option ‘To upload multiple attachments from GOS’ to avoid repetitive steps.


To add a new service in GOS toolbar. we need to add an entry in table ‘SGOSATTR‘. Since we are gonna create option for multiple attachments. Below steps indicate how to add new option in GOS for multiple attachment as ‘Create Multiple Attachment’.


New Service Create Multiple Attachment

Follow below steps to have new service under Create option as Create Attachment Multiple

  1.  Go to SM30 T-code and open table ‘SGOSATTR’. You will see something like this.Table%20View%20SGOSATTR
  2. Now double-click on record named ‘PCATTA_CREA’. This option is nothing but the ‘Create Attachment’ under ‘Create’ option.Create%20Attachment%20option%20details
  3. Now click on the ‘Copy As’ button/F6 next to ‘New Entries’ and update it according to below image. Update the ‘Name of service‘ as per you and mainly update ‘Class f.Gen.Service‘ to ‘ZCL_GOS_SERVICE‘ new ABAP class from T-code ‘SE24’ and update the ‘Next Service to ‘RESUBMISSION‘. Make sure to unflag both ‘Control‘ and ‘Commit Required‘.Create%20Attachment%20Multiple%20option%20detailsFor details of each option refer to link 1 in reference section
  4. Now Double Click on option ‘BARCODE‘ in the table and Update ‘Next service’ option to ‘PCAT_CREA_M‘ this is the name for Service ‘Create Attachment Multiple’, so that it is visible after the ‘Enter Bar Code‘ option under ‘Create‘ option in GOS.BARCODE%20option%20details
  5. Now edit the ABAP class ‘ZCL_GOS_SERVICE‘ which we have created in step 3. Inherit the class ‘CL_GOS_SERVICEZCL_GOS_SERVICE
  6. Now go to Methods tab and redefine the method ‘Execute’ and add the following code in the method.Methods
        DATA: lt_file_table  TYPE filetable,
              lv_rc          TYPE i,

          MESSAGE s042(sgos_msg).
  7. If you want this new option to enabled for only certain T-codes, then redefine method ‘CHECK_STATUS‘ and additional code for enable/disable based on conditions.

for more details regarding methods to redefine and inheritance refer link 2 in reference section


Now you will get new option in GOS as below.



When you click on the new option, you can select multiple documents and upload it together.


GOS Attachment list.


We can create a new GOS service for uploading multiple documents together by adding an entry in Table ‘SGOSATTR’ and also by inheriting the class ‘CL_GOS_SERVIVE’ in your class and redefining method ‘EXECUTE’.

      dear Alex,


      We have had the same requirement asked just this week by our PM departement.

      Very eager to test this out myself.

      Thank you very much for the info and for sharing this with us!!

      Hi Alex,

      Thank-you for a really good blog, it worked for us.

      I would mention one thing though, initially the attachments would load, but weren't available in the list afterwards.  And what I noticed is that the record is stored in a table called 'SRGBTBREL' - Relationships in GOS Environment, and the concatenate statement in the code above builds the contents for field INSTID_B... and one of the components had a trailing space, which was lost in the concatenate, and meant the record was ignored in the list.  I simply had to add "RESPECTING BLANKS"..

      CONCATENATE ls_fol_id-objtp ls_fol_id-objyr ls_fol_id-objno ls_obj_id-objtp ls_obj_id-objyr ls_obj_id-objno INTO ls_note-objkey RESPECTING BLANKS.


      This might help someone in the future.

      Thanks again Alex,


      Dave Stevenson

      thanks @Alex Muthu Nadar for sharing this awesome post

      getting Syntax Error as following:

      for the time being I have commented this line

      GO_MODEL Type Ref To CL_GOS_TOOLBOX_MODEL does not have SET_CHECK_ATTA_LIST method

      document creation/upload process works perfectly but sometimes it returns Error message SGOS_MSG(001)

      The service < Attachment > is not available

      Attachment List gets greyed out and have to re-enter transaction to view the Attachment List

      how I can resolve this?

      Hi Kamil Mirza ,

      can you check whether you missed the superclass step. go_model is an atttribute of this class, which would come automatically when inherited.

      Hi Alex,

      I've got the same issue. I checked the class heritage, it looks correct to me


      But there is still the error, same as Kamil Mirza


      If I comment this line, the code works fine, I can upload multi documents, that looks great.... but the uploaded documents cannot be opened ! Is that because of this commented line of code ?

      The error message while opening documents is:

      (Note that uploading/opening the same document with the "file by file" create attachment standard option is OK)


      I hope that you could help, because except for this issue, your blog was very valuable, and it helps me a lot.

      Apologies, when when I checked the same class in SAP system it has the method SET_CHECK_ATTA_LIST not sure what is reason for this missing method in standard class

      Thank you, Alex Muthu Nadar ; this post was very  helpful.

      Kamil Mirza , I immediately noticed the same error. The GO_MODEL is inherited, but its CL_GOS_TOOLBOX_MODEL type has no method named SET_CHECK_ATTA_LIST. Like you, I was able to create attachments just fine with the relevant line commented out.

      Alex, I am curious as to how you arrived at this missing method? What is its intended function?

      NOTE: I also implemented Dave Stevenson's recommendation above for "RESPECTING_BLANKS.

      Hi Joshua Belcher

      For me it was never an issue. when I checked the same class in SAP system it has the method SET_CHECK_ATTA_LIST & its functionality its to keep the attachment list active.

      I am not sure what is missing here.

      I suppose it will remain a mystery. Anyway, I appreciate your reply and thank you for the great article; your solution works well.
