Problem accessing the livecache - /SAPAPO/SDRQCR21


Hi All,

Background job for program "/SAPAPO/SDRQCR21" is failing in SAP SCM 7.0 system due to below error message.

"Problems accessing SAP liveCache"

There was no dump or any error message in SM21 at the time job failure or durig the job run. I have also checked the live cache availability and live cache was up and running during this time. Trace log shows that SCM system was able to connect live cache successfully.

I suspect this is a heap memory issue. As heap memory got exausted, work process was restarted automatically and when it tried to connect Livecache, it couldn't connect and job failed with an error "Problems accessing SAP liveCache". But the log doesn't show any reference to it.

Another blog Report /sapapo/sdrqcr21 - problem accessing liv... | SCN talks about the simliar problem, but I could not see function module /SAPAPO/OM_PEG_CAT_GET_ORDERS, so not sure whether it is relevant or not.

Kindly request you to suggest on this.
