Name	Value	Description
Default	0	Specifies to use the default behavior. Value = 0. The default value is also used if no value is set in the ConcurrencyBehavior property of the request. The meaning of “default” is interpreted differently based on the calling context.
IfRowVersionMatches	1	Specifies the behavior where an update or delete operation is only applied if the entity record in the database has the same row version as the entity or entity reference in the request. Value = 1. If no row version value is provided on the entity or entity references in the request, the request fails immediately.
AlwaysOverwrite	2	Specifies the behavior where an update or delete operation is applied without regard to the version of the record in the database. Value = 2. If optimistic concurrency is not enabled for the target entity, the AlwaysOverwrite behavior is applied.

Remarks

For the Default option, the following behavior applies based on the indicated conditions.

IsOptimisticConcurrencyEnabled	Source	Behavior
No	Any	AlwaysOverwrite
Yes	Any	AlwaysOverwrite
Yes	Web service	IfRowVersionMatches
Yes	Plug-in/custom workflow activity	AlwaysOverwrite
