4.7.1 Flight plans which are deemed to be ‘non-8.33 compliant’ will fail IFPS processing. The resultant action by the IFPS depends upon the aerodrome of departure as follows:

4.7.2 Aerodrome of departure is inside the IFPS Zone: =>FPL rejected

=>REJ message returned to the FPL originator and/or aircraft operator

Vielleicht hilft das ja weiter.
