This is accessed through Maintenance / Online Reservations / Reservation Friend / Reservation Friend Setup, Parsing tab, and click the Amp Service values mapping button.
The reservation data from Friend includes a single "Amp Service" value, with several different possible values (shown in a list here under "Friend ID"). However in Campground Master you have a different type of field or multiple fields that need to be set accordingly. Most often, this will simply be a "50A" preference field for the reservation. This mapping function is used as a parsing rule to determine which Campground Master field to set based on the Amp Service value from Friend.
The process is as follows:
1. Select (highlight) a Friend ID to map in the left-hand list.
2. Select a field from the Reservation Field drop-down list.
3. Select the Value to set field to in the next drop-down list, or enter a value. For preference fields like 50A that have pre-defined values (e.g. "Must Have" or "Must Not Have"), you should select from the drop-down list. If the field does not have designated values, simply type the desired value.
4. Click Add Mapping. The details of the mapped value will appear in the bottom list.
5. Repeat for all values that require fields to be set, then click Save.
Note that there is no need to map values if you don't need a field set for them in Campground Master. For instance if the only field of interest is 50A, then you only need to set the mapping for the friend ID's with 50 in them (and they would all be mapped to the 50A field, value set to "Must Have".
Mapping Notes
You can map multiple Friend ID's to the same Reservation Field if needed.
If you need to change a mapping, select it from the bottom list and click Delete/Edit. It will be removed from the bottom list, but it will also be selected automatically in the lists above, so all you have to do is make any changes needed and click Add Mapping again.
