SVH on Custom field

Hi John,

Thanks for your response, but am not getting to achive this task through these link.

I have another question:

How can we get the entered history of the field. example if user enter value in a field1  'AAA' and save order, again on creation of another order ,user give field1 value "BBB'. so on....

so whenever user enter any value to field1,system automatically the display earlier 5 entries would come in the dropdown.

Could you please advice how to do that.

Note: Need to applied on those Field where SVH is not working.

Thanks

Imran
