# Blackboard Gateway returns error message "Biller:CMD_FAIL[#28]Transaction failed. Unknown Error(Code = 124)."

Blackboard Gateway returns the following error message:

"Biller:CMD_FAIL[#28]Transaction failed. Unknown Error(Code = 124)."

If you see this error it means that the Pharos Station sending the request should not be sending the Include Credit Limit as this is not set to be received by the Blackboard TIA system.

To resolve this issue you need to update the Pharos Station information in the BBTIAcfg.exe tool.

Set the corresponding Pharos Station to not send the Include Credit Limit in the Pharos Blackboard TIA Gateway. Screen shot attached.
