CPQ provides an autocomplete attribute feature as a good choice for attributes with large number of textual values.
Begin an attribute values search by typing letters that are contained in the attribute value. As you begin typing, SAP CPQ searches a custom or quote table that contains the specific attribute values no matter what their position is. The list of results are limited to what you type and are sourced from custom and quote tables.
