FKKVT012 - Overview

• Message type: E = Error

• Message class: FKKVT - Provider Contract

• Message number: 012

• Message text: Reversal of item &1 is not possible

What causes this issue?

You want to reverse an item. However, reversing the item is not possible
for one of the following reasons:
The item is already valid and can therefore already have been used in
processes.
The item does not have a previous item, but it does have
<DS:TX.FICA_INFO_FKKVTHIER>subordinate items</>. If you reverse the
item, the subordinate items are no longer anchored in the hierarchy.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Depending on which of the reasons apply, proceed as follows:
RESET N1
End the item early instead of reversing it.
Make sure that there are no subordinate items for item &V1&. Then
reverse item &V1&.
