Order Management Extension is obtaining Null as EFF values when trying to use it for Internal TO

Summary:

I tried obtaining an EFF value that is populated in Manage Items using Manage Items in PDH using On start of submission Order Management Extension. I able to obtain the value and display it for standard orders created using Order Management UI. But the same code is returning a null value for Internal Transfer Orders created in Inventory Management and interfaced to Order Management.

Content (please ensure you mask any confidential information):

Able to display "Y" which is stored in the EFF for Standard Order created.

Null value for Transfer Order instead of Y created from Inventory Management.
