ProductActivity - Questions

[Carlos Martin <cmfermdp@gmail.com>]

Hi! 

I want to ask about ProductActivity, more specifically about the element "SupplyChainActivityDataLine". I want to ask if this element is used to represent an item and if I have many items I will instantiate the same numbers of SupplyChainActivityDataLine. 

Or if I should complete only one SupplyChainActivityDataLine , and then for each item I should use SalesItem element inside the  SupplyChainActivityDataLine.

And the last question is related with the StandardItemIdentification, which is the element that I should use to represent the ID number of the system and the EAN or SKU. Becouse there I have ID, ExtendedID, and BarcodeSymbology.

Thanks for your help

Best regards
