In RSSP, charge account segment not derived after update

Summary:

We have a configuration that segments of the Charge Account will get overwritten by values from REQ Line Level DFFs. While in the classic REQ UI, we can select our different line level DFFs and after saving the Charge Account will update as expected with information from the DFFs.

While testing in RSSP, after selecting the DFF values and clicking the Update button, the charge account is not updated as expected. I did SAVE for Later on my REQ, and then the Charge Account updated properly.

Step by Step screenshots show the functionality in classic vs RSSP. Its not reasonable to ask users to Save for Later, reopen the REQ and then Submit.
