Workflow Triggered Even Start Condition not satisfied

Dear SDNers,

I am facing a serious issue in PRD System.

My workflow has start events condition like Order Type = 'ZAB' and Profit_Block = 'B'. If this condition satisfies,then only my wokrflow has to be triggered.

But its not happened. For one SO, Order Type is 'ZAB' and Profit_block = ''. Even though my wokrflow triggered.

I checked at SWB_COND. Its perfect. Even at SWE2 also I checked.

I have seen the trace(SWEL). Here FM SWB_2_CHECK_FB_START_COND_EVAL didnt not throw any error and reported "Receiver started correctly".

Then how come my workflow triggered even condition not satisfied.

Please help me to solve this issue.

Thanks in advance,

Regards,

Venkat
