I am trying to get some good document clearing fundamentals of BDE and BOD.

I am looking for this knowledge to crack the task of publishing a web service that will execute AFS written to cover multiple activities in a particular manner.

Hi,

For BOD's and BDE's you can refer to document named Infor LN BODs and BDEs
Development Guide(U9215F US)

Thanks Bhushan,

I have gone through it. But the issue is I need to understand the basics of BOD and BDE which is not part of this document. I am looking for what is BDE and BOD and how do they work. Where to use what and what are the differences between them.

If you want to have a webservice on top of LN then you need to build a BDE in LN.
BOD's can only be used in combination with ION.

you need BDE. you can develop BDEs through Eclipse. In a nutshell you will have input and output. the input is what you want LN to read/process. the output is the messages/error output/resultant data. input can come from your webservice and output can go directly into LN tables as well as into your webservice.
