[SE-1661] Multi GAAP Retrocession order to create retro link when multiple IAB
Product Line:	P&C
Component/s:	MG & Reserve Orders
Fix Version/s:	SICS 4.9.4 SICS 4.9.3 SSP2

Aim of function
The aim is to make sure worksheets created by the MultiGAAP Retrocession Order can be automatically closed, even if the Outward Cedent's Contract is protecting multiple Assumed Businesses and the 'Mandatory Retro Booking Detail Link' system parameter is selected.
This has been done by adding a new column in Assumed Businesses window on an OCC. The new column is labelled "Source Assumed Business". The column will be defaulted to 'No'. It can be set to Yes on one of the protected Assumed Businesses.

When an Assumed Business has value 'Yes', this will be automatically selected as Source Business and linked to each detail created by the Multi GAAP Retrocession Order, and on manually created worksheets on the OCC. Other Orders, e.g. Instalment Orders will NOT use this new column.
If no Assumed Business has 'Yes' in the new column, the link to the source assumed business will have to be set manually, unless there is only one protected Assumed Business.
