Synopsis

Having difficulty formatting information within your crystal reports? Maybe you need to limit your records being display per page.

Solution

Create a manual running total to count the records in the Details section. The running total consists of two formulas: @Reset and @Details.

Example An order must be printed with only 6 records per page.

1. Create the @Reset and @Details formulas:

@Reset - this formula goes into the Page Header. It resets the counter to 0 when SCR moves to a new page.

WhilePrintingRecords;
NumberVar counter := 0

// declare a number variable and assigns
// it a value of zero

@Details - this formula goes in the Details section. It counts each record.

WhilePrintingRecords;
NumberVar counter;
counter := counter + 1

//increments the variable by 1 for each record on the page

2. Use the @Details formula to conditionally force a "New Page After". Every time the counter reaches the sixth record, it moves to a new page and prints the next set of six records.

• Go to Format | Section, and select the Details section.
• Click the "X+2" button beside the "New Page After" option (do NOT check the New Page After box). This opens the Condtional Formatting Formula Editor.
• Enter the following condition:
  {@Details} = 6

This formula forces a new page every time CR reaches the sixth record displayed on every page. The count resets to zero on every page because of the {@reset} formula in the Page Header.
