Successfactors - Employee Central Business Rules.

• Create a business rule to generate position code using the Get Next Value() function as mentioned in the KBA 2352610 - Position Management: Automatic Generation of Position Code
• In the business rule, the Get Next Value function uses a sequence object to fetch its next value.
• On creating a position, an error is thrown as below:

Call function 'getNextValue' with parameters [com.successfactors.ruleengine.gorule.bean.model.Sequence@7ca22306]. Result: 'null'. Duration: 21 milliseconds. [Error] [Error: getNextValue( toTypeInstance( "go_mdf",  "Sequence",  "PG-FO-SubSectionExtCode" ) ): [key=Exception thrown in rules execution, values=[com.successfactors.ruleengine.ruletrace.RuleTraceException: Trace already opened.]]]

• This can also be present in the rule execution log.

NOTE: The issue can arise where ever there is a business rule assigned which is using the Get Next Value() function.

• This can happen if there is an onSave rule in the 'Sequence' object.
• The engineering team has fixed this bug the 1802 release.

• In b1802, engineering team introduced a new provisioning opt-in for a new implementation of the rule function getNextValue().
• Please enable the provisioning flag "Enable the new implementation of the 'getNextValue' function for Rule Engine". If you do not have access to provisioning, please open a support case under the component LOD-SF-EC-RUL with your permission to enable the same.
• For b1802, this new provisioning flag was introduced for certain customers who faced data center performance issue due to which this was not included in the release notes.
• From b1805 release, the new behavior will be universal for all customers and the provisioning flag will be removed.
