Hi Akhilesh,
You can find below code in BuPaDetB2BVS.htm page of ICCMP_BP_DETAIL
<thtmlb:button id = "reset"
onClick = "reset"
enabled = "<%= enable_cancel %>"
iconSrc = "<%= lv_icon_url %>"
tooltip = "<%= otr(CRM_IC_APPL/CANCEL) %>" />
Set enable = "TRUE" for reset button to be always enabled.
Thanks
Richa
