Need customization for 'Reserve Orders' Program

Hi Oracle Support,

One of our users requested to modify the program 'Reserve Orders' to create a new program to run manually for required sub inventories. User want to run the program manually by providing two additional parameters;

'Ship From sub-inventory':

• Ship From Field- This field will define what sales order lines to reserve against the Pick From Sub-inventory.  The Ship From sub-inventory can found in the sales line.  Users will be typically selecting one of the Finish Goods sub-inventories for their location.

'Pick From sub-inventory':

• Pick From Sub-inventory field will define which which sales lines to select for reserving.
