My company does not use Material Determintation Conditions, but below is how to find additions/changes in SAP if there is not a standard program for this.
1) Go to table CDHDR via transaction SE16 and enter the transaction code(s)in which you are interested (VB11, VB12) and the date range. Don’t forget to change the default “Maximum no.of hits”. When you execute this you will get a list of Change Document Headers which includes the Doc #’s, User ID, Time, Date, etc.
2) Copy the Doc #’s and go to table CDPOS and paste the Doc #’s and execute the program. The system returns a list of the changes that were made includeing the field name, new value and old value.
If no one is allowed access to transaction SE16 in Production (a contentious issue) a program will have to be written to do the job.
