How To Fix RD145 - Delta update no longer possible due to realignment

RD145 - Overview

• Message type: E = Error

• Message class: RD - CO-PA Connection to SAP BW

• Message number: 145

• Message text: Delta update no longer possible due to realignment

What causes this issue?

Due to a realignment, the hierarchical assignment of characteristic
values to other characteristic values in Profitability Analysis
changed. For example, customer A was reassigned to customer group B,
but was previously assigned to customer group Z.
Aggregates (summarization levels, summarization data and so on), and
replicates (for example, CO-PA data in InfoCubes of the SAP BW) created
before the realignment no longer agree with the segment level data. A
delta update to the SAP BW can no longer be carried out.
If you still apply the old delta method with this DataSource, first
schedule an InfoPackage for a reinitialization of the delta method.
If you already apply the new delta method "Generic Delta" with the
DataSource, first delete die initialization selections in all
BW systems in which the delta method has already been initialized
for the DataSource. Then schedule InfoPackages for
a reinitialization of the delta method in the BW systems.
