Transaction Canceled BT 510

[Former Member]

Hello All,

I am getting many system log " Transaction Canceled BT 510" in client 000 user sapsys. There are no dumps occuring and no BTC jobs failing. the system log entry shows. can some body provide me some information about it.

============================

Failed to read step table

&CAUSE&

When a job is started, the individual steps are processed in sequenti

order. For this to function, the steps must be read in their defined

order and then processed.

The appearance of this message means that the read access to the step

in the current job failed.

&SYSTEM_RESPONSE&

The job involved cannot be started normally, and is therefore set to

status "Cancelled". In addition, this message is recorded in the

corresponding job log.

&WHAT_TO_DO&

Check the SAP system log for messages that occurred around the time o

this message. In particular, look for messages from the database

interface, which will normally describe the cause of the problem more

precisely.

If no database-specific log entries exist for this problem, please

contact your SAP system administrator for further analysis.

Hello Kiran,

While deleting any entries you need to be careful enough. Please first check on TEST system before proceeding to DEV to avoid unnecessary complications.

you can also delete the entries from SQL level.

DELETE FROM SAPR3.TBTCO WHERE JOBNAME = 'XXXXX' AND RELUNAME = 'YYYYYY' AND SDLSTRTDT > 'YYYYMMDD'

Please note that SAP will not advise and support if anything goes worng.

when you got SM21 error log "Transaction Canceled BT 510", did you check SM50, SM12, workprocess logs and alert SID log to drill down the issue further?

Thank you,

Hello Kiran,

What happened is the job entries in TBTCO have no corresponding steps in table TBTCP which gvies the error that the step table cannot be read. What you need to do is to delete the entries in table TBTCO which have no corresponding steps in TBTCP.

The job entries are in TBTCO and the steps definition are in TBTCP which are then loaded into the internal table setp_tbl when the job is run. Delete the step entry in tables TBTCP using SE16N (&SAP_EDIT in the Tcode at selection-screen) this should resolve your problem.

Thank you,

Hi,

How frequently you get this message. This may be because of a job getting canceled in SM37.

Please check if any job is getting cancelled and try to find the reason why.

Thanks Nirmal
