While editing document attachments in the report writer, its pages may break in a different place then when combined with the final report if the document margins differ from the report margins. Here's how to adjust to make it easier to see how it will print.
When editing a file in the document editor, it's using its own margin settings to format the document on screen as you work. But when printing a final report, the master Header/Footer document in the report writer page setup determines the overall margins of your entire combined report document. If the margins of your document attachment while editing are different than your master report header/footer document, this causes the difference.
Here's the Solution: Set your document attachment margins to match the report Header/Footer margins. That way your document will format on screen as you work the same as it will print when combined with the report. Use the document File > Page Setup to check the margins of your header/footer document as well as to adjust the margins in any other documents to match. You should adjust the margins in the master template of your documents so they will already be set that way before your attach them to inspections or do further editing.
Note that if your header/footer merges in something that expands the header, like your logo for instance, that might push the top margin down more than your main margin settings. So you may need to account for that when setting your document margins, perhaps setting everything slightly larger in both the header/footer and documents.
