Using Advanced Pricing in Purchasing--r12

Question

Can anyone give me the steps required to give a discount/surcharge on the PO price using Advanced Pricing. I understand that we have to set up modifiers and attach qualifier groups to such modifiers, but I'm not getting the desired results. I did not find any information regarding this in the Purchasing UG(r12).
Any document reference will be of immense help.
Thanx!!

Yes, to use Advanced Pricing in PO there are different setups involved you need to manage them well regularly, if there are frequent changes in discount rules.
Since you want to apply discount on PO Total, hence Blanket Agreements with Price Breaks (simpler alternative to Advanced Pricing) is not applicable in your case.
For the scenario mentioned it is important to know when you want to apply this discount/ surcharge. When the users are entering the PO do they already know the discount? Because apart from technical considerations you need to check for the impact on downstream processes upto the end of the cycle.
You can try to use the approach mentioned in your post using a trigger from Personalization/ a concurrent request. For concurrent request option you can try to use PO_CHANGE_API1_S.update_po but it will consider POs with Approved/ Requires Reapproval status and with restrictions. Like it won't update price if receipt exists against atleast one shipment and accrued and/ or invoice created etc. That's why "when" part of the question is important.
If you plan to use form personalization then be careful, as it may popup unwanted message windows confirming no. of
record(s) committed (as you have commit the changes). Also if you plan to update line prices directly in the form (not thru API/ backend) then there may be possible gaps. Say if there are mutilple lines & users clear some lines after query and then apply the discount then at form level it won't get applied to all lines for that PO.
Another important aspect is adjusting the line prices. As you will try to adjust line price based on total discount applied on PO total, after a price update takes place price changes will be rolled down to the shipment level for standard POs. The adjusted amount should match invoice to avoid un-matched recurring accrual entries.
