AX 2012 fields un retrieved on form, but are coming on table...

Hi,

I have created new fields for my customisation on Inventsum table in Ax 2012, in table browser i can put data and do any kind of manipulations i need, but i have used them on a form but they are coming up as unretrieved,

I have tried everyother work around  as proposed in this forum like sync, aos restart , adding new fields in place of them etc.. but still the display on the form is coming as unretrieved.

any body please suggest what can I do to overcome the issue,

thanks in advance.
