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

  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’.
