Condition types are to be deleted from pricing procedure

Question

Dear Experts,
I want to delete the condition types in the pricing procedure which are currently used on production system by my client. open purchase orders are exists, Purchase orders with GR and IR completed are also exists with those condition types.
So please guide me on what are prerequisites for deleting condition types? Which purchase order processing is to be completed before deleting condition types !
Thanks in Advance

Thanks Murlidharan !
Ya, please tell me the search for POs with condition type.
Conditions are deleted and affected the 300 POs, Approx. 600 GRs and Invoices.
it affected like -
a) PO Quantity 10 EA, Per unit price 10Rs
    Material Basis Price = 100 Rs
b) Suppose Condition ZFCP - 10%
    Condition Amount = 10 Rs.
    The total order Amount = 110
The Goods Receipt and Invoices were posted already with Amount 110.
Stock Account as well GR/IR clearing account was heat with Amount 110 Rs.
Also Goods issue has been made for those items.
Conditions were deleted after completion all above mentioned procedures.
And as the effect of condition deletion every where system is showing Amount posted only 100. Like, In PO, Stock Account, GR/IR Account and Vendor Account.
And I have to resolve the issue.
I have checked for the Subsequent debit option in invoice. but it will not work with Stock Account effect.
So only one option is there, Documents reverse (GR and invoice)
But i am Confused on that because Goods Issue has been posted for those items.
