All the posts on here seem to be about BDC Meta Man these days. Apologies for that, but it does show how hard we are working on it! After putting our Oracle integration we're reviewing what we should implement next. Please take a second and respond to the survey on the BDC Meta Man site. If you don't see the bit of functionality you'd like leave me a comment and I can get it added on to the options. Just a little to explain each bit...
1, Allow Store Procedures to be used for Methods
Create an empty Entity, and chose stored procedures to be used for methods that implement certain functionality ie Finder, Specific Finder, IdEnumerator
2, Create a wizzard for adding new methods to entities
This wizzard would include a SQL Generator that would allow you to create SQL Select statements easily for your Entities. It could also include the ability to select a Stored Procedure rather that SQL Statement.
3, Generate Insert/Update Methods within App Def files and generate web part code
The BDC is generally a read-only experience. How about we generate the Insert/Update methods for each entity and also output the necessary code to create web parts?
4, Read in App Def files so they can be edited
Does what it says on the tin!
5, Siebel as Data Source
Does what it says on the tin!
6, SAP as Data Source
Generally means improve web service integration.
