Good Morning,
Place outage.spl and outage.mod files to %SDM_ROOT%/site/mods/majic and recycle SDM services
I also attached xx_service_outage_tab_htmpl, but use it only if you have SDM14.1 and you have no others customizations in this file. Otherwise you need to add the following line after <PDM_MACRO name=dtlDate hdr="End Time" attr=outage_end_time>
<PDM_MACRO name=dtlReadonly hdr="Total Outage" attr=z_outage_total>
Please do this on testing system first if anything goes wrong simply delete outage.spl and outage.mod and recycle SDM services
