Attach files to GOS with Save, Retrieve, Delete functionality in SAP Web Dynpro ABAP – Part 1

Purpose:

Application for attaching files to GOS with save, retrieve & delete functionality in Webdynpro ABAP

Scenario:

I would like to explain the functionality of how to save,retrieve & delete files / Notes during attachments to GOS in Webdynpro ABAP application.

Please refer the below link for more info on GOS

GOS ( Generic Object Services )

Here I would consider the scenario of SAP FSRI module, and attach files / notes against a policy number.

Class: CL_GOS_API

Provides access to the GOS attachment list for applications. In the first step, the application must create an instance of the class CL_GOS_API and then register its unique application object at the same time. Currently, application objects of the categories BOR Object and Persistent Classes are supported. The attachment list can then be read, and the content of individual attachments can be read, modified, deleted, or created.

Pre-requisite:

Basic knowledge of Webdynpro ABAP,& OO ABAP

Step by Step Process:

Step 1:

Go t-code SE11 and create a custom structure YST_GOS_ATTACH_LIST as below

i.e. add a field ICON and include structure GOS_S_ATTA as below

Step 2:

Go to t-code SE80 and create a web dynpro component as below

Step 3:

Go to context tab of component controller and create a node ATTACHMENTS by using structure YST_GOS_ATTACH_LIST and set the properties as below

Step 4:

Create another node “ATTACHMENT_CONTENTS” by using structure GOS_S_ATTCONT as below

Step 5:

Go to attributes tab of component controller and create the global attributes GO_GOS & GV_USER_ACTION as below

Step 5A:

Create methods in component controller as below

Now, the write the code as below

Method: DO_ON_CREATE

Step 6:

Go to view V_MAIN and create context attribute POLICY_ID under node CONTEXT as below

Step 7:

Map the context node ATTACHMENTS from component controller to V_MAIN view’s controller as below

Step 8:

Create an input field and bind the value to context attribute POLICY_ID as below

Step 9:

Create a button “BTN_GET_LIST” and create an action “GET_LIST” and bind it to the event of button as below

Step 9 A:

Write the below code in event handler method ONACTIONGET_LIST as below

Here, we are creating an instance to GOS for the given policy number.

Step 10:

Create a table ui element TBL and bind the data source property to node ATTACHMENTS as below

Step 11:

Create the columns and bind to the context attributes as shown below

Step 12:

Create an extra column called “ACTIONS” for display, change, delete actions with SelectedCellVariant “KEY” as below

Step 13:

Right click on column ACTIONS and choose “Insert Cell Variant” as below

Step 14:

Set the variantKey “KEY” to TableMultiCellEditor as shown below

Step 15 :

Create a button for display and bind it to the action DO_ACTION as below

Step 16 :

Create a button for change and bind it to the action DO_ACTION as below

Step 17 :

Create a button for delete and bind it to the action DO_ACTION as below

Step 17A:

Write the below code in event handler method ONACTIONDO_ACTION

Step 17B:

Go to actions tab of view V_MAIN and create an action SAVE for save action on popup window for attaching notes or files. i.e. we have subscribed the button “OK” of popup window to SAVE action on view V_MAIN

Write the below code in event handler method ONACTIONSAVE.

Hello

Can you add the implementation code for method LOAD_ATTACHMENT_LIST ?

And also code to implement for events DO_ACTION and GET_LIST ?

Thx

Xavier

Hi Xavier,

Thanks a lot for going through the document in details 🙂 ... I appreciate your findings.. yah! missed to include the implementation of those methods 😕 ..

I have added the implementation code of those methods 🙂

We need to find out the minimum Netweaver Enhancement Pack level that is required for CL_GOS_API - so we can get this to work in our webdynpro development.

Hi,

As for as I know, the class CL_GOS_API is available from NW 7.31.

Hi,

Class CL_GOS_API and structure GOS_S_ATTA does not exist in our system ECC 6.0,.

What to do? do we need to activate object or patch update?

Hi John,

AFAIK,the class CL_GOS_API is available from NW 7.31. I think you might need to upgrade your system to EHP6.

Dear Ramakrishnappa Gangappa,

Thanks for u r Sharing the Good Document regarding GOS In WebDynpro. I'm Getting the all that u r shared but after upload then i want to see the attachments like(PDF,PNG,JPEG,doc..) files are converted as a raw string data type data, I'm unable to get the exact output that i have uploaded. while click on download button it's path changed like C:/FAKEPATH/KOLA.jpg. Please help me regarding this.

Thanks & Regards,

Dear Ramakrishnapppa,

Thanks for your feedback i'm getting the exact output in internet Explorer Browser with your Suggestion but in the google chrome browser and also it's work for .PDF Files. Suppose if i upload the file formats like .PNG,.DOC,.JPEG and Excel then it woks like Pdf file viewing on the Browser. If is not possible what is alternative solution for this.
