XI/PI: SAP XI Troubleshooting Guide

Here’s a list of common errors/problems in SAP XI and their possible resolutions. This Guide will help you troubleshoot your integration scenarios in SAP XI/PI. This is in no way an exhaustive list. You can add your points/ideas to this list. Please feel free to post your inputs using the comments form at the end of this article.

Cache Update Problems


Use transaction SXI_CACHE to update the Integration Directory cache. Alternatively, you can use the following URLs to update the CPA cache. Use XIDIRUSER to refresh the cache.

For complete cache refresh – http://<hostname>:<port>/CPACache/refresh?mode=full

For delta cache refresh – http://<hostname>:<port>/CPACache/refresh?mode=delta

If this does not solve the issue, check transaction SLDCHECK to ensure that connection to SLD is available. If the connection fails, check the configuration in the transaction SLDAPICUST. Make sure that the password maintained is correct and the maintained service user is not locked.

Now in the Integration Repository go to Environment → Clear SLD Data Cache. Also go to Integration Directoy and clear the cache using menu Environment → Clear SLD Data Cache.

Open the XI Start Page and click on Administration. On the Repository tab, choose Cache Overview. Refresh the cache using the buttons/icons on the right. Use XIDIRUSER to refresh the cache. Carry out cache refresh in the same way on the Directory and Runtime tabs.

If you are facing cache update problems in your BPM (say you have modified the BPM, but when executed old version of the BPM is picked up instead of the new one), run the transaction SWF_XI_CUSTOMIZING and press F9 carry out automatic BPM/Workflow Customizing.

Routing Errors

NO_RECEIVER_CASE_BE or NO_RECEIVER_CASE_ASYNC
This means no receiver could be found. Check your Receiver Determination. Activate and update cache. Asysnchronous messages can be manually restarted.

TOO_MANY_RECEIVERS_CASE_BE
More than one receiver found. Check your ID configuration to ensure that there is exactly one receiver for the synchronous message. Multiple receivers for synchronous interfaces are not permitted.

Mapping Errors

JCO_COMMUNICATION_FAILURE
Check whether RFC destination AI_RUNTIME_JCOSERVER is correctly configured

NO_MAPPINGPROGRAM_FOUND
Ensure that mapping program exists and is activated. If it exists then update the cache.

EXCEPTION_DURING_EXECUTE
This error occurs due to erroneous XML formatting. Check your mapping program and ensure that you supply valid input data.

Messages stuck in queues

Check the queues using transactions SMQ1 (outbound)/SMQ2 (inbound). Resolve the displayed errors. You can cancel the messages from SXMB_MONI. Execute LUW if necessary and avoid deleting entries manually.

Conversion Errors

Unable to convert the sender service XXXX to an ALE logical system
This error occurs in case of scenarios with IDoc adapters. Whenever you use business systems, make sure that the corresponding logical system name is maintained in the SLD.

Open your business system in the Integration Directory. Switch to Change mode. Access the menu path Service → Adapter Specific Identifiers. Click the button that says ‘Compare with System Landscape Directory’ and chose Apply. Save and activate your change list.

In case of business services, you can manually type a logical system name in the Adapter Specific Identifiers if required. This name should match the corresponding logical system name defined in the partner SAP system’s partner profiles.

Errors on the outbound side

Sometimes the link between SAP XI and the target system (say ERP) goes down and messages fail on the outbound side. It may not be possible to restart them from using RWB or the transactions like SXI_MONITOR/SXMB_MONI. In such cases, you can follow the procedure outlined in the following article – Dealing with errors on the outbound side.
