Conceptual model established by using PowerDesigner problem: cannot create key fields of the same fi-CodePudding

Conceptual model established by using PowerDesigner problem: cannot create the same field name key fields such as: establishing table T1, T1 contains a field ids, and show the ID as the key fields, establishing table T1 is successfully completed, and then establish a brother two tables T2, T2 table also contains a name for the ID field, when establishing the ID field is an error, error message is: This data item is already 2 in a primary identifier. The Normalization rules prevent from reusing This data item in another entity how to solve This problem?

Other table ID if the primary key, the same ID, ER figure believed to be the same, if the primary key is not allowed to key, suggest don't wish, you can change in the product data management (PDM)

Can be used, but to set up the first,

I use English said in English, in turn, click Tools - & gt; The Model Options - & gt; Model Settings, the Model Settings of the Data Item group box, cancel the Unique Code, check the Allow Reuse, now and then to PDM modeling,

If it is still not in the Tools - & gt; The Model Options - & gt; Model in Notation option Settings, select the E/R option in the drop-down menu is ok,
