How To Fix WU418 - Caution! Promo. already started! Follow-on functions already in process

WU418 - Overview

• Message type: E = Error

• Message class: WU - Promotion management messages

• Message number: 418

• Message text: Caution! Promo. already started! Follow-on functions already in process

What causes this issue?

The start of the special offer period has already passed, the end
date has not however been reached.
You can no longer change the date of the promotion start, listing
start and start of purchase price conditions, because subsequent
processing has already been carried out for the promotion.

How to fix this error?

You can carry out subsequent processing. You should however take
into account that validity periods for listing, prices, allocation
tables etc. are copied from the promotion and therefore cover time in
the past, although they no longer take effect there.
As a result, information can even be falsified for analyses.
