Serailization-Update not possible; event handler is locked

[Former Member]

We generate serial numbers in OER pass them to Aii and the outside partner will request the numbers from Aii. Once they apply the numbers to our product, they will send an association PML file back. We are receiving the serial association file from the external partner through PI. THe file comes into Aii correctly (SSCC pallet and two GTIN (case and bottle), we can see the pallet linked to case linked to the bottle. When the file gets passed to OER we get error Update not possible; event handler is locked in SXMB_MONI and not all the numbers will be in OER.

This does not happen with every file, one will work but the next will get the Update not possible; event handler is locked error. The data is the same, the number ranges are the same. The number range being used was uploaded from Aii into OER and is blocked in OER, could this be causing the issue?

We have looked at OSS note 1968226 but we are on service pack SCEMSRV 900 and the note applies to lower version service packs. We have increased the size of the lock table but are still getting the error.

Any suggestions how to fix?

Thank you for everyone's response, the webservice in PI had been disconnected.

Hello Rose,

As mentioned by Claire, please check application log (t-code SLG1 or /SAPTRX/ASAPLOG) if enabled.

When posting Rule proc from AII -> OER, do you use standard activity EPCIS_EVENT_SEND_TO_XI ? What customization/ custom objects do you have on AII & OER side ? Please provide more details about this.

looks like two processes are trying to update EH at the same time, causing the issue. You can take ABAPer help to debug the issue.

Also Check for locked EHs in table /SAPTRX/LOCKEDEH. Run the locked EH job (/SAPTRX/PROCESS_LOCKED_EH) to ensure that all events have been posted.

• /SAPTRX/LOCKED_PROC - Process Event Messages for Locked Event Handler
• /SAPTRX/LOCKED_PSET - Process Locked Event Handler Sets

Hope this helps.

Hi,

Is the error number is /saptrx/app_log017? Do you have any other errors in the application log?
