Revision Control

 
A revision is particular version of an Item, Bill of Materials, or Routing. Use the version control to track item quantities by item revision and specify a revision for each material transaction. We can use letters, numbers and characters such as A, A1, 2B and so on to define revision numbers. Letters are always upper case and numbers may include decimals. Revisions are sorted according to ASCII rules, therefore each revision must be greater than the previous revision number.
Oracle Inventory makes the starting revision number as zero.
When you save your item, Oracle Inventory assigns to the item the starting revision number from the Organization Parameters window.
Define Revisions

Navigation: MCR INV >Setup >Organization >Parameter > Revision, Lot, Serial and LPN Tab

 
Enable Revision Control Attribute:
Revision control is an item attribute. If you maintain the revision control attribute at the item master level, each item must have the same kind of revision control in each organization that carries the item.If you maintain the revision control attribute at the organization level, each item may have a different kind of revision control in each organization that carries the item.
Revision Quantity Control: If you select the Revision Control check box for an item, you must enter a revision number when you enter transactions for the item. If you clear the Revision Control check box for an item, you do not have to enter revision information when you enter a material transaction for the item.

Define Item in the item master and enable Revision Control: Enter the values as per the below screen shot

Navigation: MCR INV > Items > Master Items

Enter the item as MI-Rev02 and check the Revision Control checkbox and save the changes.

 
To track the revision go to Tolls > Revisions

Here system is not accepting 19, because previous number is 6 so system will accept above ASCII value of 6 number.

Once we enter revision as character A and save, again if we enter numeric value it will not accept, it will accept greater than ASCII value of A.

Attention: 
We will not be able to do any transaction without specifying a valid Revision for the item under revision control. 
We cannot change revision control when an item has on-hand quantity. 
We can have different revisions in different organizations if not defined at master level.
