Cash Flow Forecast - Error "Change to the document are only allowed in state Draft, because change management is activated"

Hi all,

When I want to run cash flow forecast, error message below is appeared.

Although when I display the cash flow forecast in the related main account, the amount still generated (e.g. I create new PO and this amount is included in the forecast).

Will this impact to my forecast calculation? If yes how should I fix this?

Thanks,

M.H.
