Security Resolution process defines the unique number of the security called security alias. A database cannot contain two securities with matching security aliases, these aliases are unique.
When is Security Resolution used?
When you load a security. The system resolves the alias by its id and type and if there is no such alias in DB, an INSERT is performed. If there is already a security in DB with matching alias, UPDATE is performed.
When you load security-related objects, such as Warehouse, Accounting or some of the Reference. If the system cannot resolve a security with incoming identifiers, load is impossible and it will return an error.
Which DB tables are used in Security Resolution?
...
Identifiers for each security are stored in SECURITYDBO.XREFERENCE (identifiers are also called xreference (or cross-reference ) identifiers or xrefs).
SECURITYDBO.SECURITY_MASTER and SECURITYDBOand SECURITYDBO.XREFERENCE tables are linked are linked with the SECURITYthe SECURITY_ALIAS field. This is a one-to-many relationship, one record in SECURITY_MASTER can have several corresponding records in SECURITYDBO.XREFERENCE table.
Which identifiers take part in Security Resolution?
Primary Asset Id, Primary Asset Type – Eagle identifier, which uniquely defines a security record. Stored in SECURITYDBO.SECURITY_MASTER.PRIMARY_ASSET_ID, SECURITYDBO.SECURITY_MASTER.
PRIMARPRIMARY_ASSET_TYPE fields.
It is always involved in security resolution regardless of config and options as the 10th xreference identifier - so As it is an xreference identifier at the same time, it is also stored in SECURITYDBO.XREFERENCE table.
Standard widely used identifiers – ticker, cusip, cusipPay, cusipReceive, isin, sedol, reuters, bloombergId, sicovmId, valorenId, cedel, internalId, cinsId, uniqueProductId, uniqueSwapId
Vendor-specific identifiers – <xId>AAAA</xId><XIdType>BBBB</xIdType>
