We are using RDNG 6.0.5 version iFIX 005 and we created one SOR for requirements and created one view for that and exported to REQIF format.We share the same REQIF file to supplier who is using polarion(Siemens) when they imported REQIF what ever the colums in the view that is not showing them and after revising the document and updated something exported REQIF file and share to supplier now in the polarion tool id are regenerating it is not updating the existing data.

Please suggest us.
