Yes, if you have data that is missing from subjects, that data must be replaced in some way. If subjects were not compliant with treatment or dropped out, they still must have their outcomes included in the analysis. Intention to treat is not a specific function or analysis within SPSS, it is a principle by which data that may be not be "perfect" can still be included in any analysis you may choose to do.
