How to fix this error?

Please note that the update date has changed, and if necessary take
account of the resulting changes to the assignment of business volume
data to a period (in the case of arrangements settled periodically).
This procedure ensures realtime settlement accounting for business
volumes.
The document date of the material document or invoice verification
document is used as the update date in the case of updating at the time
of goods receipt or invoice verification, or the delivery date of the
schedule line is used as the update date in the case of data updated
from the purchase order/delivery schedule. In the case of Settlement
Management documents (supplier billing documents and settlement
documents), the posting date (billing date) is used as the update date.
In some cases, the update date is changed to the start or end date of
the arrangement validity period if the original date is not within the
arrangement validity period (e.g. as a result of a data input error).
In the case of arrangement settled periodically, if the update date
falls in a period for which settlement accounting has already been
performed, business volumes are assigned to the next period for which
settlement accounting is due. The update date is changed accordingly.
This procedure ensures realtime inclusion of business volumes during
subsequent settlement.
For invoice verification documents entered in Release 3.0, the posting
date of the invoice verification document is used for the subsequent
update of business volume data. The "Document date" field in the PO
history is empty in the case of these documents.
