Example: Mapping HIPAA X12 to XML
This example illustrates how to map a file which contains an "837-Q2 Health Care Claim: Dental" transaction to an XML target file. It is accompanied by a mapping available at the following path: <Documents>\Altova\MapForce2022\MapForceExamples\HIPAA_837D.mfd.
HIPAA_837D.mfd
The mapping can be created as shown in the steps below.
Step 1: Add the source HIPAA X12 file to the mapping
1.On the Insert menu, click EDI.
2.Select the collection "HIPAA.X12", and the message type "837-Q2 Health Care Claim: Dental".
3.When prompted to supply an instance file, open the source file available at the following path: <Documents>\Altova\MapForce2022\MapForceExamples\837-Q2.x12.
4.When prompted, adjust the settings of the newly added HIPAA X12 component if necessary (for more information, see EDI Component Settings).
Step 2: Add the target schema to the mapping
1.On the Insert menu, click the XML Schema/File, and open the 837-Q2.xsd file from the <Documents>\Altova\MapForce2022\MapForceExamples\ directory.
2.When prompted to supply a sample XML file, click Skip and select DentalClaim as the root of the target document.
Step 3: Add a function to format the date and draw the mapping connections
In the source HIPAA file, the DMG segment includes a date, in the format 19490501. To convert this date to a format suitable for the target XML file 1949-05-01, we will add a date conversion function, as follows:
1.Drag the parse-date function from the Libraries window into the mapping. For more information about functions, see Add a Function to the Mapping.
2.On the Insert menu, click Constant, and enter [Y,4-4][M,2-2][D,2-2] as constant value.
3.Draw the following connections:
From | To | Purpose |
|---|---|---|
Constant | format input item of the parse-date function | Supplies to the function the format according to which the date should be parsed. |
F1251 | value input item of the parse-date function | Supplies to the function the actual value to be formatted. |
result output item of the parse-date function | DateOfBirth input item of the XML target | Supplies the value returned by the function to the DateOfBirth XML node. |
4.Draw the remaining mapping connections as shown in the example mapping (these are too many to be listed here; essentially, each connection copies values from the source HIPAA file to the target XML file. For basic information about mapping connections, see Working with Connections.)
