2420087 - ERROR: "Related Position is a required field/association in Object Matrix Position For Position" - Employee Central

When configuring an onInit or onSave rule to create a Matrix Position row, the rule is triggered correctly when a Position is created; however, an error occurs when attempting to save the new Position:

"Related Position is a required field/association in Object Matrix Position for Position."

This error is repeated for every Matrix Relationship row created through the onInit/onSave rule. For example, if the rule generates two Matrix Relationship rows, the "Related Position" is added to both, but the same error appears when saving.

If an onInit/onSave rule or a rule that copies fields to Position is configured to add Matrix Relationship rows to a new Position upon creation—using either of the methods below—the following error message will occur:

"Related Position is a required field/association in Object Matrix Position for Position."

Scenario 1
Matrix Relationship "Type" rows are defaulted when creating a new Position.

• The "Set" condition is used in the THEN part of the rule to add a Matrix Relationship row to the Position.

• This action only adds the row; the "Related Position" must still be specified before saving, as this field cannot be null.

Example:

Rule Result:

 

Scenario 2
Matrix Relationship "Type" rows are defaulted when creating a new Position, and one of the rows includes a predefined Position.

• The "Create" condition is used to set the Related Position for a specific Type.

NOTE: Do not set "Related Position" to be equal to NULL when using "Create" as this value cannot be set to Null

Example:

 

Rule Result:

The error message is triggered when attempting to save a new Position when using onInit/onSave rules as they are not supported. 

The related enhancement request is tracked under ticket MDF-13952, which is not planned or fixed for now.

The only available solution is to assign the rule to a required field as onChange. Ideally, the rule should be linked to a field that is consistently updated when creating or modifying a Position.
