Re: Restrict Work order for a specific equipment category

I believe your best bet is to use the Authorization Group and, for the roles, the Authorization ObjectI_BEGRP in conjunction with your Equipment Category (placing the burden on data maintenance and consistency)

- or -

see if you can have a custom check programmed in the exit IWO10033Customer-Specific Authorization Check Maint./Service Order

See:

Equipment category and Authorization (4.6C) | SCN
