There are several alternatives with certain disadvantages.
1) Use the select expert to conditionally restrict the records in the report. The main disadvantage in this case is, of course, the loss of data, probably related to other parts of the report.
2) Solution 1) using a subsection integrated into the main report. The problem in this case is formatting limitations
3) Use grouping. I.E. group by mytable.field uses the total number of records in the records with the group and insert into the group header. Hide the group selectively via the section specialist. Here again comes the problem of additional formatting constraints.
4) Finally, if you have access to the actual database. Create a view, it will be the best solution in terms of performance and formatting issues in Crystal reports. However, creating a view every time this problem occurs can pollute your database with views that will not be used often.
