A composite association establishes a parent-child relationship where the child (destination) object's lifecycle is dependent on the parent. To enforce this dependency and maintain data integrity, the system validates that the destination object is configured to inherit its effective dating from the parent. The "From Parent" effective dating setting ensures that the child object's effective-dated records are synchronized with the parent's records. The child object's effective start date is automatically derived from the corresponding parent record, making this configuration mandatory for a valid composite association.

B. "Basic" effective dating would allow the destination object to have its own independent timeline, which violates the principle of a composite relationship.

C. "Multiple Changes Per Day" also creates an independent timeline for the destination object, which is not permissible for a dependent composite child.

D. "None" signifies a non-effective-dated object. A composite child must be able to align with a potentially effective-dated parent, making this option invalid.

" under the sub-topic for "Composite" associations

the documentation states: "The destination object must be an effective-dated object with the Effective Dating property set to From Parent." This is a mandatory system validation. (Source: SAP SuccessFactors HXM Suite

2. SAP Help Portal - MDF Object Relationship: The guide on MDF development principles explains that for one-to-many composite relationships

the child object's effective dating must be set to 'From Parent' to ensure that the child records are always tied to a specific version of the parent record. (Source: SAP SuccessFactors HXM Suite
