Interfaces and EDI and IDOC
Well, if in an organization, there is only SAP for all the business applications, (for all modules) then will there be any INTERFACE? and will the terms such as EDI and IDOC will find their place in such cases? (since, IDOC is the data container via which data is transferred across the interfaces)
If the Vendor or Customer of that Organization has a different software application, other than SAP, then also it should not matter. since, the Vendor or Customer may receive their Purchase Orders or Sales Order via printout(fax) or email. (pdf format).
My question is very silly, but I need to know to clear my concepts. Please advise.
