How To Fix IO416 - A character string in the worklist is not a direct special successor

IO416 - Overview

• Message type: E = Error

• Message class: IO - Plant Maintenance: Object List

• Message number: 416

• Message text: A character string in the worklist is not a direct special successor

What causes this issue?

During overflow of a numerical part of the serial number, the system
checked whether the second serial number is directly consecutive to the
first number. Therefore, when the print editing was called the check
was set to the second number in the character set. This means, for
example, that in the case of serial number "AD999B", serial number
"AD001C" is checked, and not "AD000C", if the character set for numbers
is given with "0123456789".

System Response

The system does not allow further processing.

How to fix this error?

The print editing of serial numbers is used, for example, in the print
programs for printing delivery and sales documents. Check the call of
the print editing of serial numbers in your program. During an overflow,
remove the indicator for the transfer to the second character.
