In order for the transaction distribution to work properly, make sure the corresponding rule is always placed last within its flow. To apply weights, you must include a condition with the field `txn_currency`. The rule may include other conditions with other fields.`txn_type` field is disabled in the **Field** drop-down list if the weights distribution is applied. The rule will be automatically applied to payment and authorization transactions. The conditions with logical operators In set and Not in set must not be used in the rule for transaction distribution by weights.

If the rule is updated (gateways are removed/added, the ration is changed), the distribution restarts. - [Admin Panel User Guide](https://help.ecomcharge.com/en/knowledge-base/admin-panel-user-guide?hsLang=en#main-content) -
