A database commit was blocked by the application.
Please see st error for more details about the possible cause of this runtime error and how it could be avoided.
To avoid inconsistent data, an application component can forbid database commits for certain phases of program execution. If a program attempts a database commit while commits are blocked, the program will terminate, and runtime error BLOCKED_COMMIT occurs. An application component has blocked execution of the database commit. A database commit should be executed now. Execution has therefore been terminated. The block was performed for a database connection with the logical name '<runtime parameter>'.
Basis component bgRFC also blocks general database commits in order to guarantee integrity while processing units. Execution of bgRFC units is therefore all terminated when database commits are blocked.
