Insert multiple keyword into a Category via Impex

[datacol]

Hi everyone,

I am not able to associate multiple keywords to a specific category using an impex.

I wrote my impex by following the idea written in this post in the community:
https://community.sap.com/t5/customer-relationship-management-q-a/how-to-insert-a-keyword-and-relate...

The impex I wrote is:

--------

$productCatalog=dcCommProductCatalog
$productCV=catalogVersion(catalog(id[default=$productCatalog]),version[default='Staged'])[unique=true,default=$productCatalog:Staged]
$lang=Language(isocode)[default='it']
$category=source(code, $productCV)
$keyword=target(keyword, $lang, $productCV)

INSERT_UPDATE Category2KeywordRelation;$category;$keyword;$lang
;271;A pressione:en;
;271;A scomparti:en;

--------

The problem I am facing is that only one of them is kept.

Thanks in advance for any suggestion

NB: I'm using SAP Hybris 6.5
