Hello Saurav,
Creating several different conditions will not determine more than 1 free goods item.
Only one condition record is taken into account during the free goods determination with the existence of several valid condition records. This record is the one with the largest minimum quantity. For this record the system only generates one free goods sub-item.
May be you can check by creating BOM with 2 subitems and making sub items as free. But I am not sure how system will behave for normal material and BOM material.
Regards,
Bhavin
