Element locator 'not found' in SAP apps

Hello, I’m new to Robot Framework,
I’m trying to automate data input in a SAP program, but I’ve run into an issue where elements in the main area can’t be located, while there’s no problem with the elements in the menu (navbar). The elements are unique, and I’ve even tried using nested locators, but nothing seems to work.
Do you have any suggestions?

Here’s the exception I’m getting:
Exception has occurred.
Suspended due to logged failure: Element with locator ‘xpath=//table/tbody/tr/td/div/table/tbody/tr/td/div/table/tbody/tr[1]/td/table/tbody/tr/td/div/table/tbody/tr[3]/td/table/tbody/tr/td/div/table/tbody/tr[1]/td/table/tbody/tr/td/div/div/div/div/div/table/tbody/tr[1]/td/div/div/table/tbody/tr/td[2]/span/span[@id=“WD4B-btn”]’ not found.

i has attach image, the red area is the element i cant locate, the wording with red underline is the element i want to click. after click will reveal 2 choice i need to click (functional location, equipment).

Thanks before
