Need a field of 10 digit, and with a drop down table, in any infotype

Hi there,

I need to migrate one customzied field to a standard field of SAP standard infotype. It should be 10 digit long, and have a drop down table, which means I can add my customized value into this drop down table.

There are so many infotypes and fields. Till now, I haven't find a matching one. So I'm here asking for helps.

Any one knows where such kind of field is?

Many thanks!
