TPDA291
- DB commit or rollback is not permitted within an RFC ?The SAP error message TPDA291 indicates that a database commit or rollback operation is not permitted within a Remote Function Call (RFC). This error typically arises when a function module that is executed remotely attempts to perform a database commit or rollback, which is not allowed in the context of an RFC call.
Cause:
- RFC Context: In SAP, RFC calls are designed to be stateless and do not allow for database transactions to be committed or rolled back within the RFC context. This is because the RFC is meant to be a lightweight call that does not maintain a transaction state.
- Function Module Design: The function module being called may have been designed to perform database operations that include commits or rollbacks, which is incompatible with the RFC execution model.
- Transaction Management: The calling program may be trying to manage transactions across multiple systems or contexts, which can lead to this error if not handled properly.
Solution:
- Modify Function Module: If you have control over the function module, you should remove any commit or rollback statements from the code. Instead, handle the transaction management in the calling program.
- Use BAPIs: If applicable, consider using Business Application Programming Interfaces (BAPIs) that are designed to handle transactions properly and are RFC-compliant.
- Transaction Handling: Ensure that the calling program manages the transaction. Perform the commit or rollback in the calling program after the RFC call has completed.
- Check for Updates: Ensure that you are using the latest version of the function module or any related components, as updates may have addressed this issue.

By addressing the root cause of the error and ensuring that transaction management is handled appropriately, you can resolve the TPDA291 error effectively.
