Kindly give solution for this TICKET
I am facing a peculiar scenario from our client, Issue as
follows

. Customer had created Sales Order followed by Delivery and
Billing
. Credit memo request and Credit memo was created with
reference to Invoice.
. Return order and Return credit memo was created with
reference to the invoice.

Note:
During credit memo request user has changed the Base price
to “0” and added special discount to give credit to
customer.
During returns user has changed the condition value
manually to adjust the credit memo value manually, the
issue is when condition value is changed manually the value
of condition base value is not getting changed
automatically, while posting accounting document the
condition base value for Tax condition type is showing
wrongly

EX-

Sales Order-
Condition base
value Condition Value
Base price = 3,00,000
3,00,000
Tax= 21000(7% on CBV)
Invoice-
Condition base
value Condition Value
Base price = 3,00,000
3,00,000
Tax= 21000(7% on CBV)

Credit memo request-
Condition base value
Condition Value
Base price = 300000 ( “0”)
manually changed to zero)
Special discount = 100000
Tax= 7000(7% on discount since net is 0 )

Return order
Condition base value
Condition Value
Base price = 300000
( “200000”) manually changed to adjust above Cr .memo value
of 100000)
Tax= 21000(7% on CBV)

Here the requirement is if the condition value is changed
manually the condition base value needs to be changed.

While posting accounting doc the condition base value
(300000 instead of 200000) is being posted for tax.
