Data Scraping from SAP screen


I am using Data Scraping to scrape a table from SAP. While scraping after selecting the first element, it is not asking for the key to navigate. The whole table can be navigated by Scrolling. But the whole data is not getting scrapped. I have set the maximum results to 0 and even increased the Delay between pages to 9000ms.

Kindly help in this. This is occurring for similar type of tables in SAP with large data.
