Hi All,
First I want give a Shout Out to @Theo Stolker and @Rupert.Young. Because they helped me with the solution.
When you're using the EnsLib.SQL.Snapshot as a Property in the Response Message to return Snapshot data (,e.g.: from Business Operation to Business Process,) the Snapshot data won't be cleaned with the Purge messages task/service.
Class ResponseMessage Extends Ens.Response
{
Property SnapshotProp As EnsLib.SQL.Snapshot;
}
The data will be stuck in the global: ^Ens.AppData. You can find it with this query in System>Globals: ^Ens.AppData("EnsLib.SQL.Snapshot",
