Long running Delete Jobs

SQL
We have delete jobs which delete a lot of records belonging to one Version of data that runs for sometimes 2 days. The relation to this Dataversion is done by one Column in each Table whith the same value called Versionnumber. Lots of the tables are conected with cascaded deletes. How can I determine which Indexes on foreign Keys are needed to accelerate this job?

Thanks. We'll let you know when a new response is added.

I’m afraid it is a manual process.

ST05 will tell you which indices are being used.
But you will have to manually compare the code to the index, to see if it is suitable.

I stand to be educated if anybody knows a different / better method.
