Custom inventory properties not available to message scenario on inventory deinstalled event

Summary

Custom inventory properties not available to message scenario on inventory deinstalled launch condition

Content

We have a message scenario configured to Inventory is Deinstalled launch condition, where we need to pass some inventory custom properties like  I_SUBINVENTORY_CODE,I_SUBINVENTORY to external application. When we push resource inventory to OFSC from external system we pass values to above custom properties only.

 

Within message scenario body when we use these properties system does not return any value but when we use A_SUBINVENTORY_CODE,A_SUBINVENTORY properties the values in I_SUBINVENTORY_CODE,I_SUBINVENTORY are returned. Unable to understand this behavior, did anybody face the same issue? or could anybody plz help me understand how is this possible?
