Sonia,
Can you please give us some exapmles like exactly what do you mean by Sales territories and Service territories?
Then we can relate to standard JDE and find out the file ...
Also I guess F56002 is a custom file and hence that cant be accessed by us and hence we will not able to suggest you.
Please give us your rquirement in detail so that some can help you out. Also as I suggested you previuosly... since the post is related to JDE, please post the same in the JDE forum which is above so that some one might help you.
Thanks
Mark
