  Hi jsshivalik,

  Do you mention that no record exists in either of the two tables, OPCH or ORIN ?

  If there is no record in one of the tables, the result you get is null, so I suggest that you can directly judge the subtracted content by using case when, and make it equal to 0 when the return value is null, which will be more convenient.

  ps : please pay attention to some details, it doesn't need a closing bracket after the parameter like : @frDate} 

  The specific content is as follows:

  SELECT '1', CASE WHEN ( (SELECT SUM(DocTotal) FROM OPCH where  DocDate = @frDate )-(SELECT SUM(DocTotal) FROM ORIN where  DocDate = @frDate) )
   IS NULL THEN 0 ELSE (
  (SELECT SUM(DocTotal) FROM OPCH where  DocDate = @frDate )-(SELECT SUM(DocTotal) FROM ORIN where  DocDate = @frDate) 
  ) end as Amount
  

  Best Regards,

  YongQing.
