Topic: At save as - Tables Marks as Dictionary do not delete record

Sir,
Description:
I am created Database ERP software.
Side by side, I am doing actual entry and updating software as per demand raise.
In ERP Software, I have 28 dropdown menu, list is very big with records, for some dropdown menu +100.
Solution needed:
I want to preserve dropdown menu records at save as option.
May be, Tables Marks as Dictionary do not delete dropdown menu records.
Because:
Now the Database entries cross +2000
Deleting these records one by one is tedious.
Please help me with any solution with sample file.
Regards
Nitin Ingale
