How To Fix NAA635 - Update date &1 adopted (subsequent update)

NAA635 - Overview

• Message type: E = Error

• Message class: NAA - Subsequent settlement (Purchasing)

• Message number: 635

• Message text: Update date &1 adopted (subsequent update)

What causes this issue?

The condition is not contained in the document conditions of item &V4&
of Settlement Management document &V3& (supplier billing document or
settlement document). The condition was defined retrospectively.
At the time when the condition was entered, the start of the validity
period for the condition was in the past. As a result, not all
Settlement Management documents with a pricing date falling between the
date of entry and the start of the validity period could be taken into
consideration.
The condition was not taken into consideration as part of the regular
update of business volumes.
The subsequent update of business volumes has already been carried out
in an earlier program run, however. The update date &V1& determined here
was stored and is now adopted.

System Response

The system adopts saved update date &V1&.

How to fix this error?

The posting date (billing date) &V2& of the Settlement Management
document is used as the update date.
In some cases, the update date is changed to the start or end date of
the arrangement validity period if the original date is not within the
arrangement validity period (e.g. as a result of a data input error).
In the case of arrangements settled periodically, if the update date
falls in a period for which settlement accounting has already been
performed, business volumes are assigned to the next period for which
settlement accounting is due. The update date is changed accordingly.
This procedure ensures realtime inclusion of business volumes during
subsequent settlement.
