Hi Nava,
Apologies, I didn't notice that in your screenshot.
If you are entering it manually then my assumption is that you would be entering at header level only since you have marked it as 'Header condition' also.
Please check with entering 'B' in field 'StrucCond.' field under block 'Control Data 1'.
I have never tried that.
I still believe that instead of Calculation type 'B', you should use Calculation Type as 'C'.
Please revert back if field 'StrucCond.' worked/not worked for you.
Regards
SD
