Hi SriLalitha,
LC_APPL_ERROR can have many different causes.
In general, in the output of the FM you can find in ET_RC[]-RC what is the return code of the error that happened in the liveCache.
You can, then, execute transaction /SAPAPO/OM10 and check what is the short text of that return code.
Please, check if you can find out the return code of the error and what is its meaning. This should give you a hint on what's wrong and how to avoid the error.
Regards,
Tiago
