variable exists in sc_item_option_mtom but not show on the RITM form

[Qiutong Hou]

I used a script to copy records on sc_item_option_mtom table so I can have the same variable(that submit by user) for another target RITM.
I check records are created as expected on  sc_item_option_mtom table with different Parent Item, but these newly created variables are not showing up on the target RITM. 

This catalog item has no ui policy or client script. The 'Variable editor' is there in the form layout.

Would someone help me identify the issue? Thanks sooo much!

Here is my script if it helps:

I am facing the same issue. What do you mean in order?

I didnt get it.

my solution is to make sure the 'Item' filed on RITM is not empty, then the variable will show up.
