Add Attribute Fields to Relationship Tables in ArcMap

This topic contains step-by-step instructions on how to create the relationships in ArcMap. Subsequent relationship topics only include the relevant properties to choose while building the relationship.

In ArcMap, right-click the DHFC geodatabase and choose New > Relationship Class.
Under Name, enter the relationship class name.
For Origin table/feature class, select the applicable table.
For Destination table/feature class, select the applicable table.
Click Next.
For Relationship Type, choose Simple, then click Next.
Regarding the Forward Label, it must match the label in the Schema.xml. If using the default values:
1. For the Forward Label, type RFCouplerPort
2. For the Backward Label, type RFCoupler
3. For the Message Direction, choose None (no message propagated)
  IMPORTANT: The Forward Label you type while creating the relationship must match the EsriBuiltName entry in the Schema.xml file for this component:
```
<Relationship CoaxName="RFCouplerPortData" EsriDesignName="SECom.ARCFM.RFCouplerPort" EsriBuiltName="RFCouplerPort" />
```
4. Click Next.
For Cardinality, choose 1–M (one to many), then click Next.
For Relationship Attributes, choose No, I do not want to add attributes to this relationship class, then click Next.
For the Primary Key, choose NetworkId.
For the Foreign Key, choose CouplerId.
Click Next.
Review the summary, then click Finish.

IMPORTANT: With the as-built relationship complete, you can repeat the steps to create the in-design relationship. Make sure you relate the in-design components together (the ones with the suffix _D) and ensure you change the Forward label to match the Schema.xml.
