[ic] O-oh: IC newbie customizing inventory control

[interchange-users@icdevgroup.org (marc.brevoort)]

Hello group,

At our company we are trying to customize the inventory control of 
interchange to fit our needs. (More background info is in the end of this 
post).

I'm customizing order_status.html. This allows button 'Ship checked order 
lines, send email to customer if appropriate' to nicely log the amounts being 
shipped. I would like the buttons 'Update status of line N' to do the same, 
but where can I find the code that handles the update?

Viewing the page source shows the following HTML for the button:
<INPUT TYPE=submit VALUE="Update status of line 1"> 

The FORM tag says 
<FORM METHOD=POST 
ACTION="http://localhost.localdomain/cgi-bin/store/ui.html....";>

Page ui.html does not exist anywhere on my machine, how do I find out which 
page Interchange loads instead? (The same goes for process.html)?

Regards,
Marc Brevoort

We want our inventory process to closely match reality: Our inventory table 
represents the real (physical) stock. When the order status changes, the 
amount of items involved is logged. These numbers are used to calculate how 
much items *should* be in stock. The stock changes are regularly confirmed 
after which the inventory table is updated to represent the actual stock 
again, and the logs are cleared.
