IS-U : Problem in parallel processing

Dear Experts,

I am facing problem in running the parallel processes like FPVA(Dunning proposal run), EA26(Parallel Invoicing). It is showing error "There are no internal numbers which have not been assigned". I have set the all the number ranges for individual processing, mass processing.

Can anyone let me know if there is some special setting required for that.

Regards,
