Hi Sam Shiz,
Please, use to do the configuration for the country Peru, the path:
> SPRO-> Cross Application components -> General Application
Functions -> Cross-Application Document Numbering-> Chile, China,
Peru -> Assign Document Classes to Document Types or you can use
the transaction SM30, table V_T003_B_I.
2) No, you don´t have any impact for the outher countries that are
using the same document type.
3) The program do a check by country and company code. You don´t have
any impact for both countries. You can use different document class for
the same document type, because this customizing is via country code.
For more information, please, check the our website
"http://help.sap.com/" and search by country "PERU".
If you´ve more questions, please let us know.
