TPM1 issue

   Hi Experts,

I have issue in valuate using the transaction code TPM1 it will show me the error message as Scheduled business transaction with posting date xx.xx.xxxx  before key date. I have executed transaction code TPM18 before running this transaction code in that it is showing the message has there is no scheduled business transaction to execute.

Let me know how to come out from this error and get the position valuate using the transaction code TPM1.

Thanks !

Regards
