@PottipalliG6037 Create an internal data table and store your expected drop down values. In that new table, have a separate column for the sorting order. In that sorting order column, provide the order of the sequence to be displayed. Create a list type data page with a report definition to fetch the values from the table. In the report definition, sort the expected results using the sorting order column. Now, the drop down will display the values based on the sorting order you've mentioned in the table.

Are the values a local list or prompt list? If the values are in a data type, the sort order can be a columns as Rajasekar explained and that can be displayed using a Report definition specifying the sort order for this column.
