PS 1.7. URL schemes not working correctly

[samo70]

Hello, I am trying to set URL scheme for products. There are these keywords required: {rewrite} {id} {id_product_attribute}

 

This scheme is working correctly: 

{rewrite}{id}{id_product_attribute}

 

I tried also these schemes, but they are not working, I just get page not found notice :

{rewrite:-}{id}{id_product_attribute}

{rewrite:/}{id}{id_product_attribute}

{rewrite}-{id}{id_product_attribute}

{rewrite}/{id}{id_product_attribute}

{rewrite}{:-id}{id_product_attribute}

etc.

 

I just want to separate "rewrite" from "id", this was normal at older PS versions.

 

Thankyou for help
