Using the ForceCase Property of a Field to Force Case Sensitivity
You can use the ForceCase property of a business component field to force case sensitivity. If the user steps off the record, then Siebel CRM applies the case that is defined in the ForceCase property. If the ForceCase property contains no value, then the text remains in the same case that the user uses when this user enters the text.

Set the ForceCase property of a business component field to one of the following values:
