SPL XML update help

Hi all,

I had classified positive and negative lists for business partners. Now when i update the SPL XML lists and if one of the positive partners in my existing classification has become a SPL as per the new XML update, how should i handle this scenario? will i have to run the ckecks again or will the system while update rechecks everuything?

Also please walk me what would be the impact on the GTS system when we carry out SPL XML list update from data providers.

Also what precautions should be taken...

Thanks,

Raj
