I have no experience in this area of NFe. I was guided by the support as initial testing using the function:
RecepcionarLoteRpsSincrono(const nfseCabeMsg: WideString; const nfseDadosMsg: WideString):
WideString;
My question at the moment is what the WideString parameter should pass, an example to test.
Type: nfseCabeMsg: = 'xyz'; nfseDadosMsg: = 'abc';
So pass as function parameters. The examples I have are the full XML but since I must use the precise function I know which snippet I pass for each parameter.
