isConcurrent 

A parameter that governs the flow of transactions. Unlike
the security and timing parameters it does not govern the internal flow
of a transaction, rather it determines whether at run-time multiple
instances of that Business Transaction Activity can be ‘open’ at the
same time within any Business Collaboration instance performed between
any two partners. isConcurrent limits the ability to execute multiple
BTA of the same BT across Business Collaboration instances (with the
same party), or within the same Business Collaboration if multiple paths
are open. As a result, when isConcurrent is set to false, the BSIs of
each party are responsible for serializing these Business Transaction
activities.
