Unicode Project Procedure
We are about to embark on a combined upgrade and unicode conversion project. However, I am unsure about exactly which procedure to adopt. SAP's guide recommends creating an "ABAP Preparation System" being an upgraded copy of Production which has been unicode'd. In this system they say you correct all your unicode non-compliant custom code and then create a single transport of all the corrections which is then included in the upgrade of subsequent systems.
However, another approach says to use the "ABAP Preparation System" to simply generate a list of all your unicode non-compliant custom code which you then correct in your 4.6C DEV prior to upgrading it.
My final thought is could you not simply upgrade and covernt DEV and then fix in place all your unicode non-compliant custom code in place, eliminating the need for the "ABAP Preparation System"?
What approach do those undertaking or who have completed a CU & UC project?
