These rules are described in the B1 certification page:http://scn.sap.com/docs/DOC-8590 and specifically the Test Plan document:http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/206767e1-8f64-2c10-49ba-aeacbfdd528c?quicklink=index&overridelayout=true section 3.4 Modifying SAP Business One Data.
The same applies while doing all these modifications in SBO_SP_PostTransactionNotice andSBO_SP_TransactionNotification. Refer to SAP Note 1320484 for the same.
