I am using DFFS and would like to set a field value using a rule. The problem I have is that the field I wish to use is brought through as part of a look up. The primary lookup field is TOC – standing for Time off Category – and the additional field is called Absence Category. I have established that SharePoint is using the name TOC:Absence Category as the field name, with an internal name of TOC_x003a_Absence_x0020_Category. If I use that internal name in the rule that sets the value of a field called Category, all I get is the text {TOC_x003a_Absence_x0020_Category}. I have tried all sorts of combinations without success. I would appreciate your input to advise if this is possible.
