You can create Custom transformation procedures that run on 32-bit or 64-bit Integration Service machines. Use the following steps as a guideline when you create a Custom transformation procedure:
In the Transformation Developer, create a reusable Custom transformation. Or, in the Mapplet Designer or Mapping Designer, create a non-reusable Custom transformation.
Generate the template code for the procedure.
When you generate the procedure code, the Designer uses the information from the Custom transformation to create C source code files and makefiles.
Modify the C files to add the procedure logic.
Use a C/C++ compiler to compile and link the source code files into a DLL or shared library and copy it to the Integration Service machine.
Create a mapping with the Custom transformation.
Run the session in a workflow.
This section includes an example to demonstrate this process. The steps in this section create a Custom transformation that contains two input groups and one output group. The Custom transformation procedure verifies that the Custom transformation uses two input groups and one output group. It also verifies that the number of ports in all groups are equal and that the port datatypes are the same for all groups. The procedure takes rows of data from each input group and outputs all rows to the output group.
