• Message number: 429

• Message text: No change number could be generated for the selection date &1

What causes this issue?

When filling the dangerous goods master, change statuses of
specification data and identifiers are determined. To do this, the
system determines whether a change was made without a change number in
the period before the selection date. If this is the case, the system
generates a change number, executes a record split, and creates an
additional data record with validity from the selection date.

System Response

No change number could be generated for the selection date of filling
&V1&. This means no record split could be executed at the selection
date.
