Generic Extractor problem!

Hi,

I need to use Generic Extractor to extract data in the table: FPLT. While creating the Generic extactor for table: FPLT and saving the extractor, i am getting error message "Invalid extract structure template FPLT of DataSource ZFPLT"

Can any one help me out, how can i resolve this error?

Thanks & Best Regards,
