Change to Alternate Purchase Part
Explanation
Use this activity to change the quantity of a purchase part if
you want to substitute it with an approved alternate part. This feature is useful if,
for example, you are informed by a supplier that he or she cannot deliver the required part in time
but that other parts are available as
substitutes.
Note: Alternate parts cannot be specified for purchase orders with
order code 6 (External Service Order), nor for purchase order lines showing a
value in the Cust Order No field.
Prerequisites
 - The alternate part must have been defined in the 
	Alternate Purchase Part Base Data window.
- The combination of purchase part and supplier must have been established.
- The purchase order must have Planned, Released, or
  Confirmed status.
- The purchase order 
line
must have
  Released or Confirmed status.
System Effects
The original part order line will have its quantity changed to the value you enter in the
Add/Change Alternate Parts  dialog box. If the quantity is changed to zero (0), the line will be canceled.
The alternate part(s) for which you have entered a new quantity will be added to the purchase order, and the original part number will be added as a reference to the lines.

Procedure
To substitute a purchase part with an alternate part, perform the following
steps: 
  - Open the Purchase
    Order window and click the Part Order Lines tab.
- Select the purchase order line for the part you
    want to replace with an alternate. Then right-click and click Add/Change
    Alternate Parts. The 
	Add/Change Alternate Parts  dialog box
    appears.
- The header of the  dialog box
    shows purchasing
    information for the original purchase part.  In
    the Quantity field, change the quantity of the primary part.
- Go to the table to enter
    information about the alternate part(s) you want to order. All
    available alternate parts are identified in the Alternate Part No
    column.
- In the Quantity field, enter the quantity of
    the alternate part. The default value is 0 (zero). If you enter a number
    greater than zero, a purchase order line for the alternate part is added to
    the Part Order Lines tab of the 
	Purchase Order
    window.
- The purchasing unit of measure, shown in the Purch
    U/M field, appears automatically, as does the value in the Price U/M 
    field, which indicates the unit of measure used in pricing.
- The value shown in the Discount (%) field
    reflects the discount percentage received from a supplier agreement or from any price list, standard price, 
    purchase group per supplier, or supplier. You can modify the existing value
    or, if none exists, enter one.
- The value shown in Additional Cost field
    shows the fixed charge or additional fee that the supplier receives for handling the 
  purchase order line,
  expressed in the suppliers currency. Again, you can modify the existing value
    or, if none exists, enter one. Note:
    You can also enter or change the additional cost directly 
  on the purchase order line.
- Once you have completed steps 6 and 7, the total
    cost for the line is shown in the  Total field.
- If applicable and desired, enter the revision number of the part
    you want to buy in
    the Part Revision  field.
- When you are done, click OK. This returns you to the
    Purchase
    Order window.
