Items for transfer have different date of service/posting date

What causes this issue?

You selected several items for transfer, but they have different dates
of service or different posting dates. Since the posting date or date of
service is the basis for determining the option rate, the different
dates could cause the input tax distribution to be incorrect.
If you did not enter the date of service explicitly, the system uses the
posting date.

System Response

It is not possible to select these items together. Transfer items with
the same date of service or posting date together.

How to fix this error?
