Vendor confirmation tab update using idoc ORDERS02

Question

Hi all,
This is the first time i am working on idocs.
I have a requirement where i have to update the vendor confirmation tab in ME22n(Purchase order), I am using IDOC type ORDERS02. and i am using segment E1EDP20 to update quantity,date and reference no. This is working fine.
Now i need to update 2 more fields in the tab i.e confirmation category(EKES-EBTYP) and Date category of delivery date in vendor confirmation(EKES-LPEIN).But i dint find these fields in segment E1EDP20.
My question is whether these 2 fields are available in any other segment?
or should i extend the segment  E1EDP20 ?is it the correct segment to be extended...
Please provide the inputs....<removed by moderator>
Regards,
Greeshma.

Hi,
I have a questions for you and that will help me provide better solution .
a) Is vendor providing you the Confirmation category or are you expecting to get this information from Vendor ?
There are many points at which this information can be entered in ME22N.
1. When the Vendor Acknowledege your PO(If the Acknowledgment required is selected) .
2. When the Vendor request a change in schedule due to his own priorities .
3. When the Vendor actually does a goods issue and you are ready to do a Goods receipt.
In all these cases you update the system with confirmation category .In most cases this is the last phase of PO processing where you do the goods receipt and simultaneoulsy update the confirmation category. You are geting the quantity and the date updated from your schedule lines currently and since Schedules lines does not contain the confirmation category you are not getting it in E1EDP20.Confirmation category in most business scenarios is a mere stastical data rather than concrete data like schedule lines.
Depending on 1/2/3 you should be approching the solution. 1.If you want to update the confirmation category during the Order acknowledgment Use BAPI_PO_CHANGE and call it from the PI or middleware  or(3) if during the Goods receipt then call the Exit of MIGO to get the PO populated if not exit then write a custom program to see all the Goods receipt and update the PO confirmation category accordingly (Remember this is a statstical data ). Although i highly doubt that the confirmation category will be provided by vendor it is the Buyer who will be determining it and that is why it is not there in the Standard Idoc.I shall not prefer the IDOC extension.
You can have a discussion with your Functional/Customer to figure out the best approcah. Word of Caution : Analyze before you extend an Idoc .
Thanks,
