Re : previous entry i MARV table

hai

I m having an issue regarding an t-code MMPI.Posting Date was modified through TCode MMPI/MMPV many times. In MARV table I can able to find only last changes, but I need all the changes with user name and date. Now i want to trace or find log of that MMPI/MMPV t-code who had modified the t-code and the details about the modification.

In which t-code or table I can find the log details or log details How to do this ?

Thanks
