Profit center was set to &1

What causes this issue?

You entered profit center &V2& or transferred it from a previous
transaction, such as material receipt from an external order. However,
the system derived profit center &V1& from the account assignments.

System Response

The system automatically determines the profit center from the assigned
profitability segment, cost center, order, project, network, sales
order, or cost objects. This overrides the profit center you entered
manually.

How to fix this error?

To post the data to profit center &V2&, assign the profitability
segment, cost center or other object to that profit center as well.
If the posting to profit center &V1& is correct, no further action is
necessary.
