3009557 - It is impossible to use option "Retain Efforts and Quantities for Common Months" when extending Work Package via API

When extending the Work Package in the Customer Project from the UI (via app Plan Customer Projects), it is possible to choose below 2 options.

However, when extending the work package via API /CPD/SC_PROJ_ENGMT_CREATE_UPD_SRV, it will always update with "Retain Total Efforts and Quantities" by default.

Call API /CPD/SC_PROJ_ENGMT_CREATE_UPD_SRV/WorkPackageSet to update the duration of Work Package.

Currently, there is no option to use "Retain Efforts and Quantities for Common Months" in the API.

You may submit a feature request following KBA 2716534.
As a workaround, before updating the duration, using entity "Resource Demand Distribution" to retrieve the distribution data for common months first.
After extending the duration , using the retrieved data to update the distribution data back to before.
