Impact of Support Package Upgrade on languages

Dear Experts,

We have our client with SAP CRM enterprise, ISA and MSA implemented in various countries and many languages (HU, PL, CZ, N, GR etc). We would like to know if SP (Support Package) upgrade will have any impact on the languages.

Any pointers or help would be grateful. Since we need this information urgently, any help in this regard would be of great help.

Points will be rewarded for useful answers.

Regards,

Kathir
