  The SAP error message RSDMD102, which states "Error while accessing lock table RSDMDENQ," typically occurs in the context of SAP BW (Business Warehouse) when there are issues related to the locking mechanism used for data modeling or data extraction processes. This error can arise due to various reasons, including database locks, issues with the transport of data models, or problems with the underlying database.
  Causes:
  
  Database Locking Issues: The lock table RSDMDENQ is used to manage locks on data models. If there are long-running transactions or if a previous transaction did not release its lock properly, it can lead to this error.
