Yes. As long as you do not require separate matching on block type information, the CTM service provides linking of allocations or confirmations. To link each of the allocations or confirmations, set the following fields in the TradeDetailLinkages composite:
- TDReferenceType = COMM
- TDReferenceValue = Same identifier in each linked allocation or confirmation
The below visual shows the TDReferenceType and TDReferenceValue elements for one linked allocation (TradeDetail). You will need to provide the same values on all allocations or confirmations that you would like to be linked.
