Thanks for speedy response Biju. I note that you are the person who provided the original answer to this problem. I am very fortunate to have you respond so quickly. 
I didn't say that there was a new issue. I was looking for information as to whether anyone had followed your original advice and successfully implemented this.
Given that Standard SAP does not support this, I thought perhaps there may have been other complications which would have prevented the design intent from being realised, hence I was keen to hear from anyone who had actually done this and whether it had been successful, or whether other obstacles were encountered.
