Re: what is meant by set up matrices ,atp matrices ,simultion version in live cache

THere are overall versions, and you can copy these and view the data in both SNP and PPDS (or DP as well)

then there are specific simulation versions with the PPDS tool.

See below link.

So it saves a version of the production orders. Saves it in livecache and then can either be used or discarded.
