• What is the cause and solution for SAP error message DMCLG354 - For pool and cluster tables no precalculations can be created ?

  The SAP error message DMCLG354 indicates that precalculations cannot be created for pool and cluster tables. This error typically arises in the context of SAP BW (Business Warehouse) or SAP HANA when dealing with data modeling and extraction processes.
  Cause:
  
  Pool and Cluster Tables: In SAP, pool and cluster tables are special types of tables that are used to store data in a compressed format. They are not designed for direct access or for creating precalculated data, which is why this error occurs.
  Data Modeling Restrictions: The data model may be attempting to create precalculated data for a structure that is not supported, such as a pool or cluster table.
  Incompatible Data Sources: The data source being used may not be compatible with the precalculation process.
  
  Solution:
  
  Avoid Using Pool and Cluster Tables: If possible, avoid using pool and cluster tables in your data model. Instead, use transparent tables that are designed for direct access and can support precalculations.
  Change Data Source: If you are using a data source that is a pool or cluster table, consider changing it to a transparent table or a different data source that allows for precalculations.
  Review Data Model: Check your data model and ensure that you are not trying to create precalculations on unsupported structures. Adjust your model accordingly.
  Consult Documentation: Refer to SAP documentation for specific guidelines on data modeling and the limitations of pool and cluster tables.
