You can increase the efficiency of healthcare representatives and reduce manual errors
by configuring dosage specifications for a medication product associated with a
program

A dosage comprises the following key components:

* [Dosage
  specifications](https://servicenow-prod.fluidtopics.net/1rSIwz~7Sr~1es5k_aMRWQ#hcls-dosage-concept__section_xwz_z3x_htb)
* [Dosage
  characteristics](https://servicenow-prod.fluidtopics.net/1rSIwz~7Sr~1es5k_aMRWQ#hcls-dosage-concept__section_ur1_bjx_htb)
* [Dosage characteristic
  groups](https://servicenow-prod.fluidtopics.net/1rSIwz~7Sr~1es5k_aMRWQ#hcls-dosage-concept__section_cl5_qjx_htb)

{#hcls-dosage-concept__ul_j1x_1qx_htb}

To learn about how dosage components are linked to each other, see [Dosage characteristics mapping](https://servicenow-prod.fluidtopics.net/1rSIwz~7Sr~1es5k_aMRWQ#hcls-dosage-concept__section_fwn_cjx_htb).

## Dosage specifications {#hcls-dosage-concept__section_xwz_z3x_htb}

A dosage specification consists of diagnosis details and dosage characteristics of a
medication product associated with a program. For more information, see [Dosage specification table](https://servicenow-prod.fluidtopics.net/Ws2nFyEFotP6MQ7CzbtsLw "The Dosage specification [sn_hcls_dosage_specification] table stores the information about medication product dosage associated with a program.").  
Hinweis:  
When you add a dosage specification for a medication product, an equivalent dosage definition entry is added in the application. A dosage definition models a dosage specification for use as a request definition parameter. For more information, see [Dosage definition table](https://servicenow-prod.fluidtopics.net/4boiRPYToRHzHmF7nPZ9Vg "The Dosage definition [sn_hcls_dosage_definition] table models the Dosage specification [sn_hcls_dosage_specification] table for use as a request definition parameter.").

## Dosage characteristics {#hcls-dosage-concept__section_ur1_bjx_htb}

A dosage characteristic defines the attributes of a dosage specification.

A dosage characteristic has the following features:

* Is included in the Dosage characteristics characteristic group and a characteristic group mapped to a field in the Dosage details section of a medication prescription form.
* Can include a characteristic option to restrict the characteristic value. For example, to restrict the quantity of dosage. Else, when a characteristic option isn't specified for a dosage characteristic, a healthcare representative can later fill the corresponding field value in the Dosage details section of the Medication Prescription form.
* Is unique for a characteristic group when multiple entries for a characteristic are created. For example, when a dosage specification includes quantity characteristic as quantity per month supply, you can't add another characteristic for the quantity per week supply.
* Similar dosage characteristics are stored in the Characteristic Group \[sn_prd_pm_configuration\] table.

{#hcls-dosage-concept__ul_dkf_2fx_htb}  
Hinweis:  
For each dosage characteristic added to a dosage specification, a dosage variable is automatically created. A dosage variable is displayed as a dynamic field in the Dosage characteristics section of the Medication Prescription form. For more information, see [Dosage variable table](https://servicenow-prod.fluidtopics.net/V3TpyQsaB5R3Klmkgmt_5w "The Dosage variable [sn_hcls_dosage_variable] table stores the variables configured for a dosage specification displayed on the Medication Prescription form of a Healthcare and Life Sciences Service Management application.").

## Characteristic groups for a dosage {#hcls-dosage-concept__section_cl5_qjx_htb}

A dosage characteristic group comprises the similar characteristics of a dosage specification.
Each dosage characteristic maps to a field in the Dosage details section of the Medication
Prescription form. For a dosage characteristic to appear with a dosage specification, you must
include it in the following characteristic groups:

* A characteristic group mapped to a field in the Dosage details section of a medication prescription form.
* The Dosage characteristics characteristic group available by default.
{#hcls-dosage-concept__ul_r14_vpx_htb}

## Dosage characteristics mapping {#hcls-dosage-concept__section_fwn_cjx_htb}

You map a dosage characteristic group with a field in the Dosage details section of the
Medication Prescription form. You can use the
DosageCharacteristicsMapper extension point to configure the mapping
between a characteristic group and a field in the Dosage details section of the Medication
Prescription form. For more information, see [Configure the mapping between a dosage characteristic and a dosage details field](https://servicenow-prod.fluidtopics.net/VH4Eqf6crKmg0BskyDudmw "Use scripted extension points to decide which dosage characteristics are mapped to the fields on the Dosage details section of a Medication Prescription form.").

By default, the application provides a few sample characteristics and characteristic groups
for the Healthcare and Life Sciences workflows that you can as a reference when
creating a dosage specification.  
The following figure illustrates the default mapping between characteristics and characteristic groups of a dosage specification, and the mapping between characteristic group of a dosage specification and dosage details fields of a medication prescription.Abbildung : 1.
