• What is the cause and solution for SAP error message M+026 - Delta updating is active in LIS ?

  The SAP error message M+026 "Delta updating is active in LIS" typically occurs when there is an attempt to perform certain operations in the Logistics Information System (LIS) while delta updating is active. This can happen in various scenarios, such as when trying to delete or modify data that is currently being updated in the delta queue.
  Cause:
  
  Delta Update Active: The primary cause of this error is that delta updating is currently active for the data you are trying to manipulate. Delta updates are used to transfer data from the source system to the data warehouse or reporting system incrementally.
  Data Locking: The data you are trying to access may be locked due to ongoing delta updates, preventing any modifications or deletions.
  Configuration Issues: There may be configuration settings in the LIS that are not aligned with the operations you are trying to perform.
  
  Solution:
  
  Wait for Delta Update to Complete: The simplest solution is to wait until the delta update process is completed. Once the delta update is finished, you should be able to perform the desired operation without encountering the error.
  Check Delta Queue: You can check the delta queue to see if there are any ongoing processes. Use transaction codes like LBWQ to monitor the delta queue.
  Stop Delta Update: If you have the necessary authorizations and it is appropriate to do so, you can stop the delta update process temporarily. However, this should be done with caution, as it may affect data integrity.
  Review Configuration: Ensure that the configuration settings for the LIS and delta updates are correctly set up. This may involve checking the settings in the relevant InfoSources and InfoPackages.
  Consult Documentation: Refer to SAP documentation or notes related to LIS and delta updates for any specific guidance or troubleshooting steps.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as LBWQ (to monitor delta queues), RSA1 (to access the Data Warehousing Workbench), and RSCUSTV10 (to check delta settings).

  User Authorizations: Ensure that you have the necessary authorizations to perform the operations you are attempting, as lack of permissions can also lead to errors.
