How To Fix V4139 - Transferring old schedule lines is not possible.

SAP Error Message - Details

• Message type: E = Error

• Message class: V4 - Nachrichten Verkauf (Variable Meldungen und EDI-Meldungen)

• Message number: 139

• Message text: Transferring old schedule lines is not possible.

What causes this issue?

In the electronic data interchange (EDI) message, the forecast delivery
schedule key has been set to <LB>1</>, or the requirement status key has
been set to <LB>B</>.

Item field E1EDP10-LABKY (forecast delivery schedule key) has been
transmitted in the IDoc with '1' or schedule line field E1EDP16-BSTAS
(requirement status key) has been transmitted in the IDoc with 'B'.

This means that schedule lines from the old release should be copied
over into the new release. This transfer is however only possible if the
planning program can determine a unique scheduling agreement.
In this case however several suitable scheduling agreements have been
found.

System Response

The system terminates the planning program.

How to fix this error?

Ensure that the planning program only finds one suitable scheduling
agreement. Check whether your scheduling agreements have been uniquely
maintained according to the following selection criteria:
Customer material number
Ship-to party number
Customer reference number (customer plant)
Unloading point
Usage ID
Description
Change them if necessary.
