If you have set up a list, which is not using a thing navigation to a TI screen, but an OBN navigation, you might end up having this problem.
An OBN navigation from a list to a TI floorplan works on the web, but not on the iPad. The ID will not be parsed correctly and will look like this:
"PDI_ABSL_IDENTIFIER$ObnBackendPackedKey$<?xml version="1.0" encoding="utf-16"?><asx:abap xmlns:asx="http://www.sap.com/abapxml" version="1.0"><asx:values><PARA>000000000000000000000000000000000000000000000000002000000432</PARA></asx:values></asx:abap>"
And on the iPad it will show up like this:
The solution is actually quite simple, if you know it.
Set the attribute “Use RawValue On ThingNavigation” to true in the Data Model on the Outport ID field of the source screen and the ID is passed without the XML junk.
The navigation will now work as expected on the iPad!
