Important

Microsoft Azure BizTalk Services (MABS) is being retired, and replaced with Azure Logic Apps. If you currently use MABS, then Move from BizTalk Services to Logic Appsprovides some guidance on moving your integration solutions to Logic Apps.

If you're brand new to Logic Apps, then we suggest getting started here:

Lists If-Then-Else example in Microsoft Azure BizTalk Services.

If-Then-Else Expression Example

There is a Zip field in the input document and a State field in the output document. If the Zip is 98052 in the input document, then the State field in the output document is updated with WA. If the Zip is not 98052, State is updated with Other.

To do this, add an If-Then-Else Expression Map Operation to the Transform:

  1. Drag the If-Then-Else Expression to the Transform Designer area.

  2. Create a link from the Zip field in the input document to this If-Then-Else Expression.

  3. Create a link from the State field in the output document to this If-Then-Else Expression.

  4. Configure the If-Then-Else Expression with the following parameters:

    Zip

    The input name will be displayed as the node name it is connected to in the input document.

    Zip

    Condition

    Zip == 98052

    Then Value

    “WA”

    Else Value

    “Other”

With this Transform, the State node in the output is populated with WA if the zip code is 98052. If the zip code is not 98052, the State node is populated with Other.

Error and Data Handling

If an error occurs with an If-Then-Else Expression Map Operation, by default, the entire Transform is aborted. This error handling behavior is configurable. See Error and Data Handling at Expressions in BizTalk Services - Usage and Examples.
