Hi Ken,
All Node Paths (on the right had side of your screenshot) need to be relative. So, for example, the node path for the Date will need to be relative to the parent.
Usually DAT is good about preserving this. What I mean is: select the Node Path of the Table, and then select the Node Path for each column (always using the taskpane), and DBXL should keep the columns paths relative to the table's path.
So in your case it looks like all the xpaths are absolute.
To fix this, I would suggest stepping thru the node paths again:
1. Select the Node Path for the table
2. Then select the Node Path for each column, making sure to use the taskpane to double click on the field you want.
Hopefully this results in relative xpaths (for example my:Date).
You could also try to manually adjust the paths (i.e. remove my:TimeSheets/ from every column's path), but I try to discourage users from typing in the node paths, since one mistake there can lead to a mapping failure.
Good luck and let us know whether this addresses the issue. Thanks.
