    Hello Hernando Jesus Urbina Perez,

    Thank you for posting your question in the Microsoft Q&A forum. 

    This error indicates a memory overflow on the SAP application server during the extraction of the massive COEP table.

    To resolve this, you must reduce the data volume retrieved in a single call by avoiding a broad filter like a full year. Instead, implement a partitioning strategy by breaking the request into smaller chunks based on a more granular field, such as the month or fiscal period. This approach significantly decreases the memory footprint per extraction call.

    Additionally, collaborate with your SAP basis team to investigate and potentially adjust the server's memory parameters. Utilizing SAP-specific techniques like partitioning or executing the extraction during off-peak hours can further alleviate memory pressure.

    Ultimately, the key is to move from a large, monolithic data pull to a series of smaller, managed requests to prevent overwhelming the SAP system's resources.
