OK here is an example of what happened in the dataset, this dataset is a
drugs description, therefore codes are associated to names and strength the
drug and packages size, etc.

Ex:
1) ndc (National Drug Code) assigned one gpi (Generic Product Identifier)

ndc: 49502007412   gpi: 44100010102005

2) ndc that has more than one gpi (9 in this specific case, why because each
gpi represent a different packages size)

Ndc: 00904161260  gpi: 44300040007440

Please let me know if that clarified my question and thank you for your
help.

Daniel, Show us simple examples of data where an observation on  'ndc'
1) does
2) does not

"have two or more gpi".

It seems that by the phrase "two or more gpi" you do NOT mean "gpi = 2"
