How To Add Slash Between Seo Friendly Url In Opencart

When i add seo friendly url on opencart like 'abcd-test' or 'abcd-test.htm' it worked. but when i added 'abcd-test/22123.htm', IT redirected to 'www.example.com/abcd-test/22123.htm' but it displayed

The page you requested cannot be found!

I already have a website in another framework other than opencart which is doing well on google ranking. but i need to move this website on opencart and i need to make same url for most of the pages. during that process my existing website have url like "www.example.com/category-s/12234.htm

so will any one facing same problem and any one have the solution for this situation.

I found the answer:

In opencart To dayplay www.example.com/test-abc/12234.htm

Here we need to have category or manufacturer with seo keyword test-abc and 12234.htm in product seo url.

Url/product
Url/parent-cat/product
Url/parent/child/product

so if I am in www.example.com/test-abc, it is category page and if I am in www.example.com/test-abc/12234.htm, it means It is product page which beloigs to test-abc category.

it work me
