I do not understand what you are saying.

You can read the input container at any time.

You can write to the output container at any time.

Why do you want to write to the output container, and read back in? Are you talking about the activity starting again?

It is not possible to transfer a workitem while it is in a running state. I am still not sure what you are doing.

The data loop connector will map data from output container to input container of the same activity, and is only useful in situations where the activity which uses the connector fails its exit condition

The only way you can get the information you are looking for would be thru an examination of the Audit trail in the Audit Database.

But you said that one should not use runtime database directly

The only table in the runtime database which is documented for use by us is the Audit Table. If you touch any other table you will probably not be supported, but you can access the Audit table. You should realize that this will affect your perfomance. Also, you can have audit data piped to an MQ Queue which would probably have less of an affect on performance.

GOOD LUCK
