Do you really restart your SAP System? Or just refresh your Browser?

If the data are saved to you Z* table, your upload is correct.

Can you post your code where you read your z* table?

[murali_ram]

Hi Chris,

Thankyou for your quick reply.

when i refresh the browser it is fine.but when i stop the sap ides server( demo server ) and again start the application.. the issue exists..

the following code helps to read ztable

data:

     Node_India                          type ref to If_Wd_Context_Node,

     Elem_India                          type ref to If_Wd_Context_Element,

     it_india                            type wd_this->elements_india.

* navigate from <CONTEXT> to <INDIA> via lead selection

   Node_India = wd_Context->get_Child_Node( Name = 'INDIA' ).

CALL METHOD WD_ASSIST->GET_ITAB_INDALV

   IMPORTING

     IT_INDIA_AC = it_india

     .

  node_india->bind_table( it_india ).

The URL is not valid anymore! You have to save the XSTRING into your Z-Table ( lv_file_content ) not the URL!

When reading Z-Table you have to create new URL

[ramakrishnappa]

Hi Murali,

You might need to invalidate the server cache.

refer the below thread

hi chris

xstring also stored in ztable as well...but how with the help of xstring i will show up the images in the alv table??? could u pls explain briefly if possible by code??

[Former Member]

Hey,

you posted already your code and there you've done that already. You're creating a URL by using the XSTRING. Did you develop the coding?

Beginning with line "CREATE OBJECT cached_response" you will generate the URL..
