How to pass value from main report to sub report?

Here's a detailed example:

1. In main report create a formula, name it, edit it with the formula editor as follows:

shared numbervar NAME := {table1.field1} + {table1.field2}

Save formula.note that you should replace the name and type of variable and a formula with ones of your own


2. Now create a formula in your subreport, name it, edit it with the formula editor as follows:

Shared numbervar NAME;
NAME

Save formula.

3. Use formula created in step 2 in your report.

This way you will have a {table1.field1} + {table1.field2} result from main report transferred to your subreport.
