Change the description of a cost centre

RDBMS : 11.2.0.3.0
Oracle Applications : 12.1.3

Hi,

What are the implimcations of changing the description of an exisitng Cost Centre?  Cost centre set up is segment 2 of a GL code combination.

e.g. 011111.2222.33333333.444444.55555.6666.00000.00000.00000.   - where 2222 = cost centre (segment2)

We want to change the description of the existing cost centre to say from AAAA to BBBB as the number itself won't be changing it 'seems' like a normal straight forward request however, I am unsure what the knock on effects might be if I go ahead.

Any Advice would be very much appreciated.

Thanks
