Automatic refresh in ALV

32 Views

hi all

I have got the below piece of code from various other posts in SDN for the automatic refresh of ALV list.

But this code does not work in ECC. Can anyone help me what is the issue with this.

TYPE-POOLS: slis. " ALV Global Types

DATA :

gt_user LIKE uinfo OCCURS 0 WITH HEADER LINE. " User info in SM04
