The file name of this type of template should be the same as the default text e-mail template file name (assignedwi.etl or availablewi.etl). These custom text e-mail templates are stored in the %OEBPS_HOME%\ebmsapps\<ptName>\templates\email\<wsName>\ folder. If this template is present, then it is given higher precedence compared to the default template file.
Additonal operations
In addition to displaying dataslot values, you can add a text in the custom template for various purposes like giving additional information about the tasks or explaining instructions to be followed. However, please note that these custom e-mail templates give you very limited formatting options.
