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

  • In the case where the incoming file for SWAP 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. The specified xref identifiers, which are configured to be used in security resolution by <assetResolutionOption>, should uniquely identify the security.

Important Note

This logic is used only if assetResolutionOption is defined in the incoming file (not in Config Security Resolution Option or default security resolution option value).

For example:

<assetResolutionOption>MATCH_ALL</assetResolutionOption>

or

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

In order to provide compatibility with cases when the swap 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 the assetResolutionOption was passed in the incoming file for swap record and the security was not resolved by xrefs.
