“Unretrieved” fields are newly created fields which AX 2012 AX by error treats badly. It may also appear if a form query does not contain a field in the datasource field list.
Try these steps to solve the issue :
1.- Recompile and restore table. Check fields with Table explorer; if table explorer doesn’t show your field(s) properly, certainly ypur form won’t do. So, if this fails, goto 3
2.- Recompile and restore form. Generate incremental CIL. Check it. If fail, goto 3
3.- Restart Ax client and retry steps 1+2. If fail, goto 4
4.- Restart AOS. Retry steps 1+2.
