  • What causes this issue?

    The MultiProvider currently being processed is being processed
    sequentially. The reason for sequential processing is &v1&. The
    relevance of &v1& is explained in the following list:
    <ZH>PROC</>: At the time of execution, not enough free work processes
    were available on the application sever.
    <ZH>NOPA:</>: MultiProvider &v2& was explicitly set for sequential
    processing (see table RSADMIN).
    <ZH>ONE</>: The MultiProvider query consists of one sub-access only so
    it is not possible to parallelize.
    <ZH>OLAP</>: The BW OLAP processor explicitly enforces sequential
    processing. This can be the result of functional constraints. A further
    reason can be that the MultiProvider query was explicitly set for
    sequential processing in transaction RSRT.
    <ZH>ITAB</>: The result ought to be materialized in, for example, a
    database table.
    <ZH>NCUM</>: The query in question is processing non-cumulative key
    figures.
    <ZH>BTC</>: The query is being processed in a backgroung process.
    <ZH>UPD</>: The query is being processed in an update process.

  • What is the cause and solution for SAP error message DBMAN150 - The MultiProvider query is executed sequentially (reason: &1) ?
    The SAP error message DBMAN150 indicates that a MultiProvider query is being executed sequentially rather than in parallel. This can occur for various reasons, and understanding the cause is essential for finding a solution. Here’s a breakdown of the potential causes, solutions, and related information:
    Cause
    
    Data Source Characteristics: The underlying InfoProviders (e.g., InfoCubes, DataStore Objects) may not support parallel processing due to their configuration or the nature of the data.
    Query Design: The design of the query itself may lead to sequential execution. For example, if the query involves complex calculations or aggregations that cannot be parallelized.
    System Configuration: The SAP BW system may have settings that limit parallel processing, such as resource constraints or specific settings in the BW system configuration.
    Locks and Contention: If there are locks on the data being accessed or contention for resources, the system may fall back to sequential execution.
    Database Performance: The underlying database may not be optimized
