The scenario describes a situation where a custom field's default value is not being re-evaluated after the initial calculation. This behavior can be caused by several distinct configuration settings at different levels.

1. (B) The trigger for re-evaluation is often a screen refresh initiated by the source field. If the dependent field (the one that changes) does not have the Refresh screen on value change property enabled, the system is not prompted to re-run the defaulting logic for other fields.

2. (C) There is a global application parameter, Application.Base.RecomputeValueOnFieldChange, that acts as a master switch. If this parameter is disabled, the system will not re-evaluate field values upon changes in other fields, regardless of individual field settings.

3. (E) The Respect User Value property is designed to preserve manual entries. If this is enabled on the custom field, the system will set the default value initially but will not override it if a user has manually changed it, even if the dependent field's value changes later.

A. "Lock Initial value" is not a standard property in SAP CPQ. The closest equivalent is "Read-Only," which would prevent any change, not just prevent re-defaulting.

D. A validity condition violation would likely result in an error message or prevent the invalid value from being set, rather than silently causing the field to retain its old value.

1. SAP CPQ - Setup and Administration Guide: The guide details the properties of custom fields.

Respect User Value: "If this checkbox is selected

the system won't overwrite the value that a user has manually entered in the field." (This directly supports option E).

Refresh screen on value change: "When this checkbox is selected

the page is refreshed every time a user changes the value of the custom field." (This explains the trigger mechanism required for re-computation

supporting option B).

2. SAP CPQ - General Application Parameters: This documentation lists system-wide settings that control application behavior.

RecomputeValueOnFieldChange: "When set to True

formulas are re-evaluated when a field value is changed. When set to False

formulas are not re-evaluated on field change." (This directly supports option C as a global cause).
