Rules and Guidelines for Custom Transformations

Rules and Guidelines for Custom Transformations

Use the following rules and guidelines when you create a Custom transformation:
  • Custom transformations are connected transformations. You cannot reference a Custom transformation in an expression.
  • You can include multiple procedures in one module. For example, you can include an XML writer procedure and an XML parser procedure in the same module.
  • You can bind one shared library or DLL to multiple Custom transformation instances if you write the procedure code to handle multiple Custom transformation instances.
  • When you write the procedure code, you must make sure it does not violate basic mapping rules.
  • The Custom transformation sends and receives high precision decimals as high precision decimals.
  • Use multi-threaded code in Custom transformation procedures.
