This error may be incurred by KCO's that are setup to handle multi-currency transactions. It will usually be seen in combination with a [108]
This indicates that the realised/unrealised variance values have to valid costing path to hit the GL.
If the parameter is blank, the transactions will route to the GL based on Module config (which an point to different GL accounts per module).
To resolve this error, ensure that this parameter is set to a valid cost code. If WBS is in use, that should be included.
The terms are bit crossed here, the Parameter refers to cost head specifically but really it requires the entire cost code for this to function. Having only the cost code nominals will stop this from working properly
