variable maps not loading records not displayed in the UI

hi,

Some context:

We use the aggregate discount matrix to auto-add the "Receive" product

simple example:

If you buy:

Product A AND

Product B AND

Product C

     then you get a Product D and E for free.

In our implementation, Product D is added automatically by a PSP workflow.

Scenario

1. End user adds product A
2.      PSP workflow is triggered, Product D and E are not added.
   
3. End user adds product B
4.      PSP workflow is triggered, Product D and E are not added.
5. End user adds product C
6.      PSP workflow is triggered, Product D and E are added. (since the rule has been met)
