Enhanced eCommerce wrong data

Question

I'm implementing Enhanced eCommerce with GTM and the measure purchase data is wrong and so many orders are not collected.

The process I've had is I implemented the code but I don't know if I have to set any tags on tag manager because I'm already gathering data, it's just not accurate.

Here is an example code:

ecommerce: purchase: actionField: affiliation: "Online Store" coupon: "" id: "69527" revenue: "37000" shipping: "8000" tax: "2394.5" products: Array(1) 0: brand: "MTR" category: "Hair color" id: "8202" name: "Hair color 2" price: "29000" quantity: "1"

Do I have to make tags in tag manager to make it more accurate?

Answer 1

It may depend on problems on the website or on a failure to return to the order confirmation page after payment.

5% less orders are physiological, higher numbers indicate a problem on the website or in the tracking.
