How To Fix BWFIAA008 - Extraction of &1 not possible - first request delta

BWFIAA008 - Overview

• Message type: E = Error

• Message class: BWFIAA - Messages for FI-AA Delta Extraction

• Message number: 008

• Message text: Extraction of &1 not possible - first request delta

What causes this issue?

You want to execute a delta initialization for source &V1&, and you
already executed initialization runs for this source in the past.
However, before you can execute a new delta initialization, the data of
previous selections has to be updated in BW.
are variables correct? mail to Klaus moser

System Response

The extraction was terminated.

How to fix this error?

Execute a delta extraction for source &V1&. This loads the current data
to BW. You can only perform a new delta initialization extraction once
the delta extraction is completed. You must perform the delta
initialization on the same day as the delta run so that there are no
gaps between the extraction periods.
Currently, source &V1& was extracted up to the date &V2& and time &V3&.
The delta initialization you requested would perform an extraction,
based on the selection criteria, up to the date &V4& and time &V3&. For
all previous data requests, the time between the two dates would not be
extracted. For this reason, you have to execute a delta request before
the delta initialization, so that previous data requests up to &V3& are
also extracted.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

BWFIAA008 - Details

• The SAP error message BWFIAA008 indicates that the extraction of a specific data source (denoted by &1) is not possible because it is the first request for delta extraction. This typically occurs in the context of SAP BW (Business Warehouse) when trying to extract data from a source system using delta extraction methods.
  
  Cause:
  
  First Delta Request: The error usually arises when you attempt to perform a delta extraction for a data source that has not yet been initialized. Delta extraction requires that the initial load (full load) has been completed successfully before any delta requests can be processed.
  Initialization Not Completed: If the initialization process for the data source has not been executed, the system does not have a baseline from which to calculate changes (deltas).
  Data Source Configuration: There may be issues with the configuration of the data source in the source system or in BW.
  
  
  Solution:
  
  Perform Initial Load: Ensure that you have
