Thanks for your response. As per the documentation "Language packs are available for Pega Customer Service in Italian, French, Japanese, German, Spanish and Portuguese".
But I have raised an SR-B86645 to install to the same on cloud environment. But they are having a difficulty or some problem to find out, so they told me to check here in the community. I feel that SR should have been assigned to some particular team and I am not receiving correct response.
I checked SR-B86645. It requested for Customer Service Language Packs (Spanish, Italian, French and German) to be installed on dt4,dt5. This needs to be done by the Pega Cloud support team.
This SR-B86645 is currently owned by Manjunath Doruboyina from Cloud support team. They will do the installation for you if there is a need.
Besides, Pega also offers a ‘Localization’ wizard capability to enable customers to localize Pega-based applications, including custom fields and screens quickly and easily, and in any language.
Pega Localization wizard is used to make an application available in additional languages. The localization process overrides text in user-visible field value rules that appear in application elements such as user forms and portal displays. The wizard automates many of the steps necessary to create language-specific rulesets.
The localization wizard is located in Designer Studio >User Interface > Localization Tools > Translate to New Language. You can do a translation for your personal rules from English to other language (eg. Spanish). The generated zip file (Translation_Spanish_2017-10-19_xxxx.zip) was downloaded in 'Downloads' folder. Later, you can import generated zip file (Spanish version) to somewhere for Spanish speakers to use.
You don't have to plugin the rulesets. According to your browser locale the appropritae ruleset will be picked to your ruleset track. Please make sure your ruleset and Nl ruleset have the same name with suffix _xx. e.g.
