Scratchpad - customers?

Hello all,

Just had a question regarding scratchpad database and wanted to understand if something should or should not occur...

Basically:

1) Is customer information persisted to the scratchpad database... I am aware transactions are... but if POS is retrieving customer information centrally via webservice (same as trn's), does it get added to the scratchpad?

2) If a transaction had a customer linked to it, when retrieving the transaction does the customer information come to the scratchpad with the transaction (in the scenario that the customer was not available at the BackOffice database for that store)?

I have read the Oracle note about how CTR works and the diagrams, but not sure about customer information...
