Having defined and imported the attribute mapping syntax to read and write values to a property on the Item Master Form, NX does not write the values to the form, nor are values being read. The value in NX shows as <no value>.
Typical attribute mapping syntax to read and write to a property on the Item Master Form:
NX Attribute : Item.GRM(IMAN_master_form,Item Master).form_property /master=both /description="Item Master Property"
If the syntax is correct, check to see if the following Teamcenter Property has been set:
If this is undefined or set to "no" then it is not possible to write to properties on the Item Master Form from NX.
