The mapper is used to map services from the LKAAT catalog to the TARDOC catalog. It is applied after the grouper has 
determined that a patient case is to be billed per individual service ("NO.ambP" group).
After mapping, TARDOC rules that are decidable given the provided information in the context of a session
are applied. Rules that require further information are annotated in the TARDOC tarpos.

Implemented rules on the level of an LKAAT service are:

- Code is valid
- Code is not a trigger position
- Code is not a duplicate in the context of the session and side.

Implemented TARDOC rules are:

- Side is required
- Master is present in slave services (Haupt- und Zuschlagsleistungen)
- Cumulation rules, all types
- Number limitations (Mengenlimitationen) that are decidable within the context of a single session
- Age limitations
- Sex limitations

Unimplemented TARDOC rules are:

- Percentage services (Prozentleistungen)
- All rules regarding the service provider (Leistungserbringer): Dignität, Sparten, ..
- All rules that need information from previous treatments: number limitations in the context of a patient's history, ..
- All rules that need information not present in the LKAAT catalog
