2lis_13_vdkon subtotal not available in communication structure

Hi All,

I want  all the subtotals(KZWI1 to KZWI6) for the Datasource 2lis_13_vdkon,try to move subtotal feilds in LBWE from comm structure to extract structure but not available

in that comm structure and i check with MCVBRP structure where all the Subtotals available in that.

So,I checked with table TMCEXCFS(LO Data Extraction: Field Status of Communication Structures) where subtotals feild status is F(Disallowed).

Please guide me how to activate subtotal feilds,I need to populate subtotals without writing any enhacement code.

Thanks,

Kishore.
