What causes this issue?

During the reimplementation of business transactions, the removal of
postdating, or the shifting of effective date, the system attempts to
transfer the original input data to the current application. The
processing or change of an object, such as a clause, limit or
deductible, can only be transferred if the object to be processed exists
in the current application. The object to be processed may no longer
exist, for example, in the following circumstances:
The object was deleted during retroactive processing.
The creation of the object was skipped on account of the settings in the
scheduling dialog.
The validity of the object is no longer defined due to the shifting of
the effective date, for instance the end date of the object is before
the new effective date.
For the external scheduling of the business transaction, an invalid
object key was transferred for object &V1&.

System Response

The input data will not be transferred to the current application.
During the reimplementation of business transactions, the removal of
postdating, or the shifting of effective date, the system interrupts the
business transactions and displays the scheduling dialog again.

How to fix this error?

The business transaction must be executed with user interaction or the
change is no longer necessary due to the circumstances described above.

Procedure for System Administrators

If the business transaction is to be scheduled externally, the
scheduling program must be analyzed.
