Chirag, you can modify the detail_***.htmpl file and use the "value" tag to give a default value when the ticket is created. For example, "
<PDM_IF "$args.id" == "0">
<PDM_MACRO name=dtlTextbox hdr="Summary" attr=summary value="xxxxyyy" colspan=3 keeplinks=yes size=120 spellchk=yes srchknow=no>
<PDM_ELSE>
<PDM_MACRO name=dtlTextbox hdr="Summary" attr=summary colspan=3 keeplinks=yes size=120 spellchk=yes srchknow=no>
</PDM_IF>
"
will give default value of the summary as "xxxxyyy". Thanks _Chi
