Understanding Related Field Fixed Table Relations in D365 F&O

What is Related Field Fixed?

A related field fixed table relation in D365 F&O is a type of conditional table relation that restricts the records selected in the related table. The condition is an equality comparison between the value of a field in the related table and an enumeration value.

For example, let's say you have a table called Products and a related table called ProductCategories. The ProductCategories table has a field called CategoryID that is an enumeration of the different product categories. You can create a related field fixed table relation between the Products and ProductCategories tables that restricts the records selected in the ProductCategories table to only those categories that are associated with the current product.

The syntax for a related field fixed table relation is:

(<EnumValue> == Table.Field )

Where:

• Table is the name of the related table.
• Field is the name of the field in the related table that is being compared to the enumeration value.
• <EnumValue> is the enumeration value that the field is being compared to.
