Hello,

I am trying to "put" data from an Opportunity into another tab object called "Batches".

I have an example of how it was done by my organization in the past using a custom link but I am not sure if there is a better way.

Here is part of a custom link within Opportunity:

It looks like in order refer to fields of an object outside the current object, you have to specify their object id.
My question is what is the "a00/e" and how do you know to use it. And what is "=%2F00630000001b2Sq".
There appears to be a "CF" in front some object ids. Is this kind of usage documented anywhere?
If this is how to get and put data between objects, is there a way to get a complete report of ALL object names and IDs to make development easier? I find it hard to believe that this is the way it's done, but I'm new with SalesForce so anyhelp would be great.

Thanks.
