WSFEX:WSFEX-Manualparaeldesarrollador_V1_1.pdf

• wsfex ticket support. I think the existing logic should work, but we need to add the URLs for it.
• Enable WSFEX for the test account.
• Extended fields (e.g.: those not already in Receipt):
  • Permiso_existe: String
  • Permisos: Optional, OneToMany
  • Dst_cmp: Mandatory, needs a foreign table for FEXGetPARAM_DST_pais (TODO: can I re-use GenericAfipType)
  • Cliente: Mandatory, String(200)
  • Cuit_pais_cliente: Nullable, Needs a foreign table for FEXGetPARAM_DST_CUIT
  • Domicilio_cliente: Mandatory, String(300)
  • Id_impositivo: Nullable, String(50)
  • Obs_comerciales: Optional, String(4000)
  • Cmps_asoc: Optional, TODO: is this like CbtesAsoc?
  • Forma_pago: String(50)
  • Incoterm: Optional, String(3), Needs a foreign table for FEXGetPARAM_Incoterms
  • Incoterm_Ds: Optional, String(20)
  • Idioma_cbte: Mandatory, Needs a foreign table for FEXGET_PARAM_IDIOMAS.
    • Can table re-use GenericAfipType?
  • Needs a new deserialiser.
  • Items: Mandatory. can we make ReceiptEntry and this converge into one? Needs a foreign table FEXGetPARAM_UMed
• When calling validate(), the logic need to fork if receipt_type == FACTURA_E.
• Write serialiser to convert our django model into AFIP XML.
• Write a parser for the response type (it looks pretty different to WSFE).
• TODO: Is the response the same?
• FEXGetPARAM_UMed
• FEXGetLast_CMP
• Are WSFE currencies the same as FEXGetPARAM_MON
• Does FEXGetPARAM_Cbte_Tipo return the same as WSFE?
• What the hell is FEXGetPARAM_Tipo_Expo???
• Some GenericAfipType have different string lengths; make this parametrisable by subtype?
• Does FEXGetPARAM_PtoVenta return the same as WSFE?

The extra fields should probably be in a separate model/table to avoid confusion (e.g.: ReceiptForExport) and have a OneToOne field to the Receipt column.

I think all new models should be in models_wsfex.py to keep file sizes sane.

Extended features:

• Expose FEXCheck_Permiso?
• Re-validate with FEXGetCMP?
