If you are using MyPMS as a Property Management System, the Item IDs must match the NAME of any 'sub-types' that you have set up in the Setup | System | Postings | Charge area of MyPMS. If the NAME of your MyPMS Item and the Item ID in the Members Area do not match, then when the Package is broken apart into Items, or an Item is sold directly from a website, that Item will not properly dowloaded into the MyPMS onto the Guest's folio. Please contact BookingCenter Support for help doing tis if you are unclear how the MyPMS system must match the BookingCenter system.
