Falcon Username limit

In FICO Falcon application we got below error.

Application opened increasing number of connections to MQ due to this error.

Aug 31, 2017 9:29:59 AM RoutingDomain DeploymentRegion Default S145215: FAFIO - Error transforming field userID in buffer caseManagementRequest207Mq, Field overflow exception for field 'caseManagementRequest207Mq.userID', connection mq://BLOCK.REQ;hostName=1.1.1.2

FICO support analyzed the issue and found that there was an undocumented username 10-character limit specified at below config file. We temporarily disabled lastly created long username 'NameSurname' user and restarted application, problem solved.

Meanwhile both we and FICO learnt this limit and FICO documented this limit afterwards :)

This UserId is defined in Buffers.caseManagement.xml
