I’m working with a Master-Detail region in Oracle APEX, and I need to export or download data from the Detail region, including a custom header in the exported file. I attempted to achieve this by storing the desired header in a page item and referencing it in the report attributes under “Supplemental Text” or “Header and Footer.” However, the exported file doesn’t include the custom header as expected.
I also followed the steps mentioned in the Dynamically Update Interactive Grid Header in Oracle APEX – Doyensys Blog but it seems we cannot use HTML within the “Supplemental Text” or “Header and Footer” sections.
Has anyone successfully implemented a similar requirement?
