Processing CAMT documents
If orders were submitted in batch mode, there are three methods to resolve the underlying transactions. Either (A) directly within the CAMT52/CAMT53 document, (B) within a separate CAMT54 document or (C) by a reference to the originally transferred PAIN message. The applied method depends on the bank (method B is most commonly used). It could be handeled differently for incoming and outgoing transactions.
