Question / Problem:
How will Confirm calculate the SettlementAmount for non X-Currency Trades?
Answer / Solution:
There is a custom setting for SettlementAmountCalculation that can be enabled on per IM basis.
It is unusual for the IM to provide settlement amount for the splits on a non X-ccy trade. IM would provide a settlement amount only if the currencies are different.
However if a IM provides the settlement amount and matches on settlement amount then it can enabled via the below setting for the IM in Party Management.
Navigate to the IM in Party Management -> Click on modify -> Enable Settlement Amount Calculation for this IM.
