Problem:
We have cases where we have a brokered business, but the claims are directly paid to the cedent. Or the brokerage is paid to the broker, but the rest to the cedent. For this, we use the assignment to the Claims Payment or Brokerage Payment task to the partner where we want the payment to go.
In the manual world this causes that on the worksheet, this is reflected in the Balance Split Option, and the worksheet is split on the different payment partner as we set it up.
However for the eMessages, this does not work. When I did swap to worksheet, there was no Balance Split Option and everything went to the main payment partner and nothing was split eMessaging should work exactly the same.

Solution:
eMessaging should take the same default and balance split settings as a manual worksheet with the exception that the settings should be derived from the specific insured period being booked on and not over the entire business. i.e. another insured period with different partners for broker / claim payment and payment tasks does not affect the current booking IP settings.
If the bookings on the workhsheet are made for a service provider then and only then should the settings be reduced to Insured Period checked only,

Workaround:

Root Cause:
Settings for EDI London Market applied generally to all eMessaging.

Extent of Impact:
B2B bookings with different payment partners assigned tasks (payment, claims, brokerage)
