Hi Jyothsna,
1) We generally go for customized IDocs if none of the SAP standard IDoc does not suit our need/business process. Creating is custom IDoc should be a very stringent process. The SAP standard IDocs should be rigorously checked (if any user exits can be of our help or IDoc extension will solve the purpose).
2) WE19 is the test tool by which we can create IDocs to see whether our functionality is working. It is mostly used to debug inbound function modules.
For outbound function module debugging you can use the following:
1) RBDMIDOC - for master IDocs configured via change pointers.
2) RSNASTED - for transaction IDocs with output/message control.
3) RSEOUT00 - For IDoc whose status is "to be processed".
Regards
Aneesh.
