How do you update another form with information from the current form?

Both forms must have a unique key field (a formula for this can be found here). There must be a hidden view of the destination documents with the first column being the unique key. Variables are passed using environment variables. This code would go in the source form's update button:
@If(@IsNewDoc; ""; @Do(@Command([FileSave]); 
@Command([FileCloseWindow]); @Return("")));     
ENVIRONMENT CTDB5 := @Trim(@Text(Qty));
@Command([OpenView]; "(SpecialView1)"; CTDB1);
@Command([ToolsRunMacro]; "(UpdateReceivedQty)");

The UpdateReceivedQty macro would then do the following:

FIELD QtyInStock := QtyInStock;
@If(UniqueId != @Environment("CTDB1"); @Do(@Prompt([OK]; "Error"; "UniqueId Number " + @Environment("CTDB1") + "cannot be found"); @Return("")); "");
@SetField("QtyInStock"; (QtyInStock + @TextToNumber(@Environment("CTDB5"))));
