I am trying to create a top down distribution cycle and after running it I have got these warning.
What are they referring to and how to fix them?

Hello 

Please check the segment definition in APP Manage Allocations.
Under 'Receiver Bases' tab, here you defined 'Reference Base' for Retained and Relevant to Reference fields.

For example: Customer Group 01/Product Sold Group L001/.../Account 5111100000, etc.

Then sender value should be distributed as reference data, when system trying to distribute value, reference data following above combination could not be found.

Best Regard,
Owen
