E-Mail layout incorrect

Dear All,

I follow Incident Management and Change Request Management: E-Mail functionality in SAP Solution Manager 7.1  Option 6.2 - Mail form definition to set my email layout.

But I check the email as you can see on Attach Files "Variable blank", I find the variable can not be display correctly.

Did those variables like "SAP_CRMS_SRQM_GEN_FIELDS-CRM_SRQM_DESC" had already change?

How should I find those variables technical name?

Thanks & regards
