Hi
If you are referring to the value date for payment requests created from IHC module, to my best knowledge, value date configuration OBBA/OBBB may not work as Payment requests have value date filled in, when created from IHC when you process the Payment orders. Please check F8BT on this.
For one client with IHC, I ended up doing user exit to correctly determine the value date of Payment requests when F111 executes it.
Hope that this helps
Kind regards
