External Invoicing in SRM7.0
When I started integrating External Invoicing with SRM7.0 there was no documentation available and SAP was not ready to support since it was not fully functional yet. There was no Standard content provided to translate proxy data. Hence we tried usual method of debug in SRM to troubleshoot the data needed. Debugging helped us figure out the type codes and the type of proxy needed to use for external Invoicing.
