Continuation on the modification in the web application to apply the logic of the business unit filter on the other filter and into the data to be extracted,  the business unit filter is applied in extracting the activity query, and the extracting of resources base on the selected business unit is created, apply the created query to achieve the logic needed when selecting the business unit (it should only show the resources under the selected business unit), checked the modified application, and as per checking the changes did not take effect, the resources filter still showing all the resources regardless of the selected business unit, checked the created query for checking why the resources is not filtered based on the business unit for fixing.
