SWAP and FORWARD Security Resolution

A SWAP record is an SMF record with processingSecurityType (tag3931) starting with "SW".

A FORWARD record is an SMF record with processingSecurityType (tag3931) "FWXXXX".

• In the case where the incoming file for SWAP or FORWARD has <assetResolutionOption>element is set to MATCH_ALL or xref identifier type (CUSIP, ISIN etc.), the security will be resolved by xref identifiers instead of resolving by primary asset id/type and swap type (for swaps). The specified xref identifiers, which are configured to be used in security resolution by <assetResolutionOption>, should uniquely identify the security.

...

• In the case where the incoming file for SWAP or FORWARD has <assetResolutionOption>node is NOT specified, the security will be resolved by common security resolution logic for SWAPs or FORWARDs based on primary asset id/type and swap type (for swaps).

In order to provide compatibility with cases when the swap or forward security was early inserted with primary asset id/type only, but the incoming file updating the record contains assetResolutionOption (e.g., <assetResolutionOption>BCUSIP</assetResolutionOption>), the W_ALWAYS_USE_XREF global parameter for w_config_custom.inc can be used. By default it is enabled (empty value equals "Y"). 

If you disable it ("N"), security resolution will be performed by primary asset id/type and swap type if type (for swaps) if the assetResolutionOption was passed in the incoming file for swap or forward record and the security was not resolved by xrefs.

Case Insensitive

Sometimes you want to force xrefs be loaded in upper case for a record to make them case insensitive. Use the following element in the incoming message:

<assetResolutionOption>CASE_INSENSITIVE</assetResolutionOption

...

<assetResolutionOption>SKIP_PRIMARY_ID</assetResolutionOption>

Use Only Security Alias as XREF

When <assetResolutionOption>USE_ONLY_SEC_ALIAS_AS_XREF</assetResolutionOption> is set, only Security Alias will be used as identifier and if resolution cannot find a Security, new Security will be created.

In case of I2I the following option in the RTR for I2I workflow can be added:

 <taskParameter>
    <name>SetAssetResolutionOptionValue</name>
    <dataType>S</dataType>
    <value>USE_ONLY_SEC_ALIAS_AS_XREF</value>
 </taskParameter>
