The preference Enable Post Result defines whether or not ESI services would initiate PostResult RPC requests for transactions in a release. The preference has relevance to closed loop transaction scenarios. When set to No, the status of each sub-transaction in a transaction (and also that of the transaction) is set to Pending (or to Failed), according to whether or not the ESI response was delivered successfully to the distribution target relevant for the transaction. When set to Yes, the status of each sub-transaction in a transaction (and also that of the transaction) is set to Succeeded (or to Failed), according to whether or not the response was delivered to the relevant distribution target. In cases where the status of a transaction was set to Failed, an ESI Failure is generated and assigned to the user. This preference has relevance only to ERP Connector. Modify ERP Connector to cater to closed loop transaction scenarios. This may be achieved by having the response data (that is delivered to a destination) processed appropriately and imported into an MES system, and sending back the results of the import to Windchill.
