Validate Field Value Mapping

This tutorial explains how to build a Segment/Field rule validating that a field transformation is based on a mapping table.

In this example, we’ll validate that PID.8 (Administrative Sex) is transformed following this mapping table:

Code Standard Code
1 M
2 F
3 U
4 U

 

  1. Create an Excel file containing the mapping table as illustrated above
  2. Create a new suite variable
    • Select the root node in the suite tree (suite name)
    • Select the Variables tab on the right
    • Click Add…  A new row is added to the grid
    • Set the variable NAME to GenderMapping
    • Set the variable TYPE to Mapping Table
    • Set the generator type to Excel File
    • Enter the File and the Worksheet the table is in
  3. In the inbound HL7 task, select the Validation tab
  4. Select the Segment/Field Validation tab
  5. Add the rule: PID.13 is = ${GenderMapping[${CxLastOutboundMessage[%PID.8%]}]}

     

    This rule tells the application to:

    • Get initial PID.8 value (${CxLastOutboundMessage[%PID.8%]}):  PID.8 value of the message just sent
    • Get mapping value (${GenderMapping[...]}): Get the mapping value in the mapping table

    In other words, the validation rule loads the mapping table and returns the mapping value (M) for the initial PID.8 field (1).
