HI Keiji,
Sorry for delay response, When i keep just one field Value as >$TABLE-7 and nothing else i get the an alert for Table SMW3_BDOC but when i add second Filter BDOC_STATE = E04 , i see the Data collector runs in Managed system and also DSWP_BPM_TIMESCH has an entry but there is no Alert generated the Monitoring Object remain Gray no result.
Not sure if the setting is right , this is how i did it when i dont get any results.
And set the Analysis tool as this
No idea where i am setting it wrong 
Since for me important thing is to find out only Error status entries in the table for last 7 days and not all entries.
Thanks,
Shravan
