There are two scenarios that need to be taken into account:

Scenario 1: Secondary request is a TLR Hold (has no itemId)

Order of actions:

• Create Secondary request

• Create Primary request (with same type as Secondary request)

• When Secondary request obtains itemId, while handling the event:

  • Create circulation item

  • Create DCB transactions

Scenario 2: Secondary request is not a TLR Hold (has itemId)

• Create Secondary request

• Create circulation item (from mod-tlr)

• Create Primary request (with same type as Secondary request)

• Create DCB transactions
