Data Deployment Error: FIELD_CUSTOM_VALIDATION_EXCEPTION:Lower Bound for block <n> must equal to Upper Bound of previous block
"FIELD_CUSTOM_VALIDATION_EXCEPTION:Lower Bound for block #7 must equal to Upper Bound of previous block"
Salesforce’s API cannot guarantee that block pricing tiers will be deployed in a particular order. However, triggers require these tiers to be deployed following an order.
In this case, you can temporarily disable Salesforce's CPQ triggers in the destination org before deploying the data template and reactivate them once you are done.
