Why Deletion of Assignment Data Through HDL is not Supported?

Summary:

Hi Team,

We see Oracle doesn't allow us to delete the assignment data through HDL. In the business object, support operation types are Create/Update for the Work Terms and Assignment Object. How ever Work Relationship object supports Deletes as well. Am trying to understand the rationale behind this design.

As we have multiple effective dated rows in Assignment level, we will get into number of situations where we may need to delete Assignment data. Why wasn't supported through HDL? Is there any other alternate methods available to handle this deletion operation?

We understand that there is a REST web service based solution to delete the Assignment data. But we are looking more of like HDL/HSDL solutioning for this.
