Purchase Order History Program - not working properly

Question

Dear friends
i am developing purchase order history program in ALV,
which shows the report of purchase order status
i.e (fields as below).
document no
PO date
line item
material number
material name
purchase org
plant
purchase group
orderd quantity
ordered amount
delivered quantity
delivered amount
to be delivered quantity
to be delivered amount
invoice quantity
invoice amount
to be invoiced quantity
to be invoiced amount
how to test from me23n
open me23n
enter PO number
press status tab
you can get some fields for verification..
the problem is
i can get all the details correctly except delivered amount and to be delivered amount
it works fine in both ( material purchase order and service purchase order )
sometimes i am getting incorrect values in service purchase order specifically in delivered amount and to be delivered amount
why i am getting these incorrect values ??
only couple of POs generate these things.
i am getting these values from EKBE table and using proper filtration like movement type and etc...
if anyone can resolve ... would be appreciable

Hi,
for getting proper Po History you need to select PO's details from EKKO table and
Header details from CHANGEDOCUMENT_READ_HEADERS based on the details got from this FM pass
to the FM CHANGEDOCUMENT_READ_POSITIONS and get proper details.
This is the logic used by the standard program also to get the PO History.
Hope this helps.
