Hi Abhinav,
HASHLOV will work as below.
1)original value is hashed to a number.
2) total number of values in seed list is divided by number obatined in #1. This will give index number.
3) By using index number from #2, value is choosen from seedlist.
Please explain the masking required so that we can suggest a other function.
some suggestions
1) Increase the values in seed list.
2) HASHLOV will work with mostly string literals.
3) You can also use XREF by constructing a table for old and new values.
Please let me know your thoughts after this, so we can discuss further.
Regards,
Raju Devolla.
