What is the maximum number of characters a task ID can contain when creating tasks in a scheduler such as Microsoft Project (MSP) or Open Workbench (OWB)?

 

Answer: 

CA PPM allows a maximum of 16 characters on task ID attribute, if tasks are created in MSP or OWB with IDs exceeding 16 characters an error will be thrown when when saving project from MS Project or OWB to CA PPM : 

 

"TASK/prExternalID exceeds maximum length of 16"
