Error MVR-RC-20: How I can Fix it with "Arcgis methode"

[Belkacemlm]

I am trying to make a relationship between two classes, so i have to define Primary Key and Foreign key , the problem is when i define The relationship classes inside Arcgis it' work perfectly, but when i want to define a UML Diagrame for the same classes and the same relationship rule inside Entreprise Architct i get this error

Error MVR-RC-20: Incompatible Foreign Key Type,pdaupos,<>,UML Connector,Path=Workspace::Features::PDAU,A Primary Key of type esriFieldTypeOID was detected. The corresponding Foreign Key must be of type: esriFieldTypeInteger.



I googled a little and i understand that i have to Add a new Field that represent The ID number for my class with esriFieldTypeInteger type.

So i have two IDS for every object : OBJECTID : esrifieldTypeOID (generated automatically). X_nameID : esriFieldTypeInteger (I have to create ot manually).

So how I fix this error please?
