MORE INFORMATION

This hotfix introduces some optimizations to Value Mapping functoids. These optimizations can be enabled by adding the new OptimizeValueMapping attribute to the <mapsource> element in your BizTalk map (.btm) file and then setting the attribute value to yes. To do this, follow these steps:

In Notepad, open your BizTalk map (.btm) file.
Add the OptimizeValueMapping attribute to the <mapsource> element. For example, your <mapsource> element should be similar to the following:
```
<mapsource Name="BizTalk Map" BizTalkServerMapperTool_Version="2.0" OptimizeValueMapping="yes" Version="2" XRange="100" YRange="420">
```
Note The OptimizeValueMapping attribute value is case insensitive.
On the File menu, click Save.
On the File menu, click Exit.
