Siebel operation insert step throwing error after 8.1.1.11.17 patchset upgrade

Hello There, We are facing an issue in our environments after 8.1.1.11.17 patchset upgrade. An insert operation done using a workflow step is throwing an error. On investigation, we could see that Required property is set to Y for the BC field but it is not set for its corresponding Table column. The input argument contains the value as expected for this field.

As per our understanding, we can set the Required property for BC field irrespective of Table column so that the field contains the value conditionally. But Oracle has recommended to remove the Required property at BC level and insisted that this property value should be consistent between BC field and Table column. If that is the case, can you please comment on how to achieve a business requirement as below.
