Bug: PEOBJEDITHOME does not work with some transformation methods
** This issue is addressed in ArcSDE 9.0 Service Pack 2 (SP2) **
The PEOBJEDITHOME environment variable can persist custom geographic (datum) transformations and coordinate systems in the Projection Engine. The Projection Engine is used in ArcSDE and ArcGIS. The Bursa-Wolf, Coordinate Frame, and Position Vector methods do not work with PEOBJEDITHOME in version 9.0.
For more information on the PEOBJEDITHOME environment variable, please see Persisting Projection Engine objects.
The Projection Engine library cannot interpret the method parameters correctly.

If you cannot apply Service Pack 2, use the following workaround:
- Use PE_MTH_MOLODENSKY_BADEKAS, rather than one of the affected methods.
- With the values set to zeroes, add three parameters to the definition:
- The Molodensky-Badekas method uses the same rotation convention as the Coordinate Frame method. If using the Position Vector method, change the signs on the x, y, and z axis rotation parameter values.
Do not use this example! It is for illustrative purposes only.
