Yes. Settlement instruction enrichment in ACWF is the same as enrichment for the block-level workflow, except enrichment is on the allocation. The direct XML interface provides enrichment on information you provide in the TradeDetail.
Include settlement instructions in TradeDetail messages so that the financial and settlement information is together in one message. Settlement information includes standing settlement instruction (SSI) enrichment from the ALERT platform. See the pdf Settlement Services Reference: SWIFT MT541/543 and CSV Mapping (4.25 MB) for more information about how to supply settlement instructions on your trades.
