Starting version 8.xx the parameter SP_OPO_GENERIC_CR has been deprecated and the value has been hard coded to 1 so it is no longer needs to be set.
The reason of using this param in earlier versions was SharePlex had Generic and basic( for individual tables) and to control the generic conflict resolution, is necessary to set this to 0 OR 1.
Now in versions 8.xx of SharePlex, it only have Generic and by default it is enabled, so no necessary to control it manually.
Do Not set this parameter. No longer exist in versions 8.x.x.
Conflict resolution implementation in 8.xx is the same as it was in 7.6.xx but SP_OPO_GENERIC_CR no longer need to be set to 1.
