I believe someone in your CO was trying the new UDF fields and did not finish them correctly.  
 
We are trying to tighten the post save validation to erase any incorrectly set up UDF's  but that version is not out yet..
 
What the UDF's do is to use a Table to define fields that get compiled at runtime in IN-A and IN-B.
 
Are you getting the same errors in IN-B too?
 
if so, use SM-P-E to edit the user defined fields.. if you are not useing UDF's then that table should be blank.

the generic ones are the defaults.. if you run it and there are none setup it adds in the generic ones.  But if you just exit it removes the generic ones thinking there was nothing really to save. But as you said you had some stuff in yours.. that was what was causing the Error.  I am working on adding Validation code to our Grid editing ( something that sounds easy, but really isn't ) All our grids are generated by a Library and Edit currently is a switch (on/off) I need to find some way to add validation code to fields in the grids that are stored in tables that the user can modify (SU-A)...
