Call Remote Function Module with SAEURI dataelement as Export parameter

Hi Experts, Am creating a program in a Gateway system, where i need to call a FM from HR system.

My Code is like this,

Data: lname(20) type c,

lv_url type SEAURI.

Call 'Z_EMP_GET' Destination 'HR_DEST'

Exporting

Pernr = '12345678'

Importing

lname = lv_lname

Url = lv_url.

At HR Destination system, I have a FM 'Z_EMP_GET ' with signature as

Importing : Pernr Type NUMC

Exporting : lname Type Char20

Url Type SAEURI(Char 4096).

When i debugged it, I see the Remote FM is getting Perner value and returning only lname, but URL paramter is empty.

I believe i have problem in receiving Long Text (URL - Char 4096).

How can i handle this and let me know if need to specify String length parameter for RFC call somewhere.

Also let me know if need more details

Thanks in advance.
