How To Fix CL148 - Date cannot be shifted to &

SAP Error Message - Details

• Message type: E = Error

• Message class: CL - Classification

• Message number: 148

• Message text: Date cannot be shifted to &

What causes this issue?

You want to <DS:GLOS.date_shift> shift</> the valid-from date of a
change master record.
This is not possible because the consistency of at least one class that
was processed with this change number would be violated on &V1&.
This could be for the following reasons, among others:
A class has already been processed with a change number that has the
selected date, &V1&, as its valid-from date.
However, a class can only be changed with one change number on any
given date.
A class has been changed with a change number that has a valid-from
date between the old and new date. An inconsistency in this
change can occur if you shift the valid-from date.
The date shift causes inconsistency in changes to classification data.

System Response

The system creates a message log listing the change objects that
prevent a date shift.

How to fix this error?

Confirm the message. If you choose the <LS>Shift date</> pushbutton,
you see a dialog box in which you can enter a new date or cancel the
date shift function.
