Adding Expressions to an IDMS Record

Adding Expressions to an IDMS Record

To return additional information for an IDMS data map record, add user-defined fields that use one or more PowerExchange functions in an expression to process source data.
These functions provide operations such as field splitting and concatenation.
You can also call the following functions to get CA IDMS/DB source data:
  • GetDatabaseKey
  • GetDataFlowType
  • GetDbKeyOfFirstMember
  • GetDbKeyOfLastMember
  • GetDbKeyOfNextMember
  • GetDbKeyOfOwner
  • GetDbKeyOfPriorMember
  • GetFullDbKey
  • GetFullDbKeyOfFirstMember
  • GetFullDbKeyOfLastMember
  • GetFullDbKeyOfNextMember
  • GetFullDbKeyOfOwner
  • GetFullDbKeyOfPriorMember
  • GetPageGroup
  • GetPageGroupOfOwner
  • GetPgGrpAndRdx
  • GetPgGrpAndRdxOfOwner
  • GetPgGrpOfOwner
  • GetRadix
  • GetRadixOfOwner
  • GetSeqWithinLevel
  • GetSeqWithinParent
Use expressions to create relational structures, such as data warehouses, from CA IDMS/DB source data. The IDMS functions that return database keys return results for both bulk and CDC source data.
You can also use the CallProg function in an expression to invoke a user-defined program to process source data.
