Problem: The option to check out data for disconnected editing from within the ArcPad Data Manager toolbar is unavailable
When attempting to check out feature classes for disconnected editing, the option to check out data for disconnected editing from within the ArcPad Data Manager toolbar is unavailable.
There are a number of circumstances that may restrict the ability to check out feature classes for disconnected editing:
• The map document and feature classes within it do not share the same spatial reference.
• Shapefiles cannot be checked out for disconnected editing.
• If a feature class has not been assigned a spatial reference system or has one that is undefined, the option is unavailable.
Solution or Workaround
In addition to checking the above criteria, the following best practices are suggested:
Pay particular attention to the period of time that data must remain checked out. Checking data out based upon a defined extent should be performed within a timeframe closely correlating to the field collection process.
Background layers cannot be checked in and this is particularly important with regard to shapefiles. While shapefiles can be copied to the mobile device via Mobile Device Manager, changes performed to these layers while in the field cannot be 'merged' with the existing shapefiles.
