Inserting Multiple Values Simultaneously into Select Options 
You can copy multiple values from a table or a text editor and paste them into the select options so that they can be used for searching. If the operator in a row is IN BETWEEN, you can enter a range of values. In both cases new rows are rendered containing the values from the copied rows. You can use the standard copy and paste clipboard functions (CTRL-C and CTRL-V).
Note
This function is generally available first in release SAP_BASIS 7.32. If you want to use it in lower releases, you have to request it.
