Hi
Unfortunately there is no easy way for this. Depends upon how much selections you are talking about , you could try following steps.
Each selection description is associated with a cryptic Selection ID which is a primary key.
Selection ID along with planning area and planning book make up the primary key.
Having said that, it should be possible using the following two tables
/SAPAPO/TS_SELKO
/SAPAPO/TS_SELPO
The latter table needs to be done first using the SE16--> "create with template" option. Once you have the selection ID created in the latter table, you can again use the "create with template" option in the former table.
Thanks
