Useful SAP Middleware transactions

[former_member182637]

SAP CRM Middleware uses Business Document (BDoc) messages when transferring data between systems.

Sometimes problem during the replication requires monitoring the Middleware. SAP offers standards tools to monitor BDoc errors messages in the system. The most used transaction is SMW01 (Display BDoc messages) accessed via menu path Middleware>Monitoring>Message Flow>Display BDOC Messages. However there are other useful transactions in the system.

Middleware Common Transactions

When checking Middleware problems, a review of configuration is necessary. The following transactions are useful.

CRM Generation

SMOGTOTAL	Generate required objects for CRM Replication
GENSTATUS	Check Status of Generation Jobs
SMOGIND	Generate Industry Specific Objects
SMQR	qRFC Monitor/ Register CSA Queue
SMOHQUEUE	Queue demon

CRM Connectivity

SALE	Define Logical system
SM59	Configuration of RFC Connections
SMOEAC	Administration Console

ERP Connectivity

SMQ1	Outbound Queue
SMQ2	Inbound Queue
SALE	Define Logical system
SM59	Configuration of RFC Connections

CRM Replication Setting

R3AC3	Adapter object overview (replication filter for customizing objects)
R3AS	Start Initial Load
R3AM1	Monitor replication status
R3AC1	Adapter Object Overview

Troubleshoot BDoc Replication

When a BDoc is not replicated successfully, is necessary to check the logs and understand the reason that causes the problem.

The following transactions are useful:

SMW01	Display BDOC Messages
SMW02A	BDoc Message Error Analysis: Sum of Errors
SMQR	qRFC Monitor
SMQ1	Outbound qRFC Monitor
SMQ2	Inbound qRFC Monitor
SMWP	CRM Middleware Monitoring Cockpit
SMWT	Middleware Trace
SMOHQUEUE	Monitor R&R Queues
SMO8REORG	Delete Processed BDocs
SMW03	Show stats of unproc. BDoc messages
SMW19	Copy BDoc and process
SMW20	Process BDocs
SMW3RBM	Convert BDoc Messages to XML
SMW3RC	BDoc Message Error Recovery
SMW3WD	Watchdog for failed BDoc Messages

Tx SMW02A “BDoc Message Error Analysis: Sum of Errors”

This transaction is useful to get a detailed error message for “BDOC type”. That allows summarising all errors founded in the system.

The result list not only show the “Bdoc Type” but also the component affected that is useful information when researching SAP Notes that could give any indication of the reason for the error.

When pressing button “Detail Analysis” system navigate automatically to transaction “SMW01 Display BDOC Messages” and displays the BDocs Message affected.

Tx SMO8REORG “Delete processed BDocs”

This transaction allows deleting BDocs logs from the system. It could be run in a test mode and filtered by BDoc Type, BDoc Message ID, User or change date/time. Cleaning the log will allow users to focus on unresolved system issues.

In summary, middleware problems are usually based on configuration. Always have a look not only to the middleware configuration but also to the component configuration.  Using monitor tools, issues in more detail could be checked and knowing the "Application Component", a better filter could be used when lookingfor SAP Notes.
