Planning combination maintenance/deletion in IBP

Dear experts,

Please help me with different options available to manage/delete obsolete combinations in S&OP 3.0 on-premise version. Requirement is to do the cleanup of many obsolete combinations hence we cannot use 'Delete combinations' option in excel plugin which allows us to delete one combination at a time.

There is operator called DELABDNCOMBOS in later versions.

Thanks,

Sagar.
