SO-Free goods found but not apply

Question

HI everybody,
Please help me solve this problem:
I've finished free goods and tested OK 2 months ago. It doesn't work when I come back and check again.
I have configed and define master data VBN1, I use free goods analysis to check, system found condition record and display "Condition record has been specified", but when I click on that condition record "The condition record for use N can not be displayed".  And no have any subsequent item under Main Item (system even don't warning when I input quantity smaller minimum quantity of free goods as in the past).
More Infor: I just use Exclusive for Free goods with the very simple way. And I still can input manually free goods by inputting higher level item no.
I have researched every topic and check config again and again but it doesn't seem to work. Please suggest me any way to continue.
Many thanks for your help.

Answer 1

Use Tcode VBN2.
Provide your Free Goods condition type - Discount type in VBN2 and click on Condition Information button.
This would take you to display condition record screen.
Don't provide/maintain any data in selection parameter & Execute.
But kee validity period/date in check.
If any condition record is maintain, then you will be able to see the result in List for Condition Type screen.
You can also follow Table KONDN - Conditions: Free goods - Data section to check whether you have any data maintained.
KONDN-KSCHL
Discount type
- Free Goods condition type
Say, NA00 - Free Goods SD
