Direct mailing campaign data must be converted from data structures 3.X to 4.0. This means that address list data must be converted from INDX entries to transparent table entries. In order to perform this conversion, you must have a system with version 3.X. If you call up a direct mailing campaign for which the selected addresses are stored in the INDX table, you receive a system message informing you that conversion program RV433C40 must be started. Use transaction SE38 to call up this program. The current direct mailing campaign is converted immediately. All remaining direct mailing campaigns that need converting are converted in the background. Contact SAP if the program log refers to errors. You cannot correct them.
You do not need to make any settings in Customizing.
