I have MPNs but no GTINs causing warnings with identifier_exists:false

Visitor ✭ ✭ ✭

I’m doing a feed for a company that has no GTIN’s but does have their own MPN’s, and mkaing changes before the May 16th cut off.

 

I submitted a revised version of their feed with ‘Identifier Exists’ set to ‘False’ for every product as articles I’ve read have suggested, for products that have no GTIN... however there is an identifier of MPN, so i'm getting the following warning on my feed.

 

"Product Identifiers provided but 'identifier_exists' set to false."

 

Is this going to cause a problem come may 16th?

 

Does submitting an MPN mean I don't need to set 'identifier_exists' to 'false', despite having no GTIN?

 

Any help would be appreciated, thank you Smiley Happy

the global-trade-data (mpn, gtin, brand) attributes
are for manufacturer's data -- not merchant data.

all merchants selling the same product must submit
the same global-trade-data or identifier_exists FALSE
without any global-trade-data.

private sku or similar merchant data are not allowed.

Hi,

i don't think like that. Because where ever you used the brand element you must need to pass your product identifier details. Else you can update that as "False" no issue in that one.

I'm in a similar boat. I have MPNs, but our industry does not use GTIN/UPC (although I still got the notification in Merchant Center.)I have the identifier_exists field left blank and have submitted MPN/Brand. But do I still need to submit a GTIN field? And if so does that need to be marked FALSE?

(a) no;
(b) no -- never.

the notification by google was posted as a warning regardless of any details.

gtin is never, ever, required unless the manufacturer
has assigned valid gtin to the exact item being sold,
to uniquely identify the item for global-trade.

gtin is required only if the manufacturer has already assigned valid gtin
to the exact item being sold, to uniquely identify the item for global-trade.

global-trade-data values (gtin, mpn, brand) can never, ever, be FALSE

global-trade-data attributes (gtin, mpn, brand) must either be the
exact value the manufacturer has assigned, or not submitted if
the manufacturer has not assigned a valid value.

only the identifier_exists attribute can be TRUE or FALSE --
to indicate if the required and valid global-trade data exist
and have been assigned by the manufacturer, or do not exist.

identifier_exists left blank is considered TRUE for a tab-delimited feed.

merchant-assigned global-trade-data is never allowed.

the rules for global-trade-data have not changed in any fundamental way --
the may16 deadline is mainly for more strict enforcement of existing rules.

(1a) has the brand-manufacturer, of the product being sold,
stamped a valid gs1 gtin bar-code on the item or package?

(1b) do the gtin and brand, together, uniquely identify
the product being sold and the product's manufacturer?

if yes for both 1a and 1b, submit both the gtin and brand attributes --
otherwise, do not submit gtin and do not submit a brand for the item.


(2a) has the brand-manufacturer, of the product being sold, stamped a
valid manufacturer-part-number on the product or package, or issued a
valid mpn to all merchants, for the exact item being sold?

(2b) do the mpn and brand, together, uniquely identify
the product being sold and the product's manufacturer?

if yes for both 2a and 2b, submit both the mpn and brand attributes --
otherwise, do not submit mpn and do not submit a brand for the item.


(3) otherwise, submit identifier_exists with a value of FALSE and --
do not submit mpn, do not submit a gtin, and do not submit a brand,
for that item-offer.

 

all merchants selling the same item should be

submitting the same global-trade-data values,

or identifier_exists FALSE if none exist.

otherwise, a merchant-center product-listing-ads support-specialist
at google may be contacted directly for account-specific guidance.
