Hi AJ,
FTR_SHOW will show you some of the tables for a Security tranaction (VTBFHA, VTBFHAZU, VTBFHAPO0. At FTR_SHOW for a Security, you enter the financial transaction number assigned via FTR_CREATE versus the Security ID. The two tables that I use most often for the ID master data are VWPANLA and VWPANLE.
Regards,
Lisa
