IDOC_OUTPUT_ORDRSP at line item level

Question

Hi All,
Scenario:  I want to issue the sales order conformation EDI output at the line item level. I set up the condition tables/records at the line item level so the BA00 output is triggered at each line item. But each IDOC has line item record for all the line items and NOT for the line item from where it was issued.
Is it possible to trigger BA00 at each line item and the corr. IDOC contains only PO1 segment for that line only ?
I want o/p at the line item as that line can be blocked/rejected (order reason code) and I do not want BA00 for that line (via the o/p reqmnt) . But if the o/p is triggered from the other line item, it contains PO1 segment for that rejected line also.
Other option is to trigger o/p from header level and check in the user exit if each line is rejected. That will be OK but what if all the line items are rejected and IDOC o/p fails and is in RED color in the o/p screen. How will the end user know that BA00 o/p failed ?
Your input is appreciated.

Thanks Again.
Only problem with the solution is that when the order is in the create mode (not saved), there is no data in XVBAP. If order is already saved and I am trying to send a order ack for a change, it will work bcos I can fill XVBAP by reading VBAP from KOMKBV1-VBELN.
But this will still help me. I am planning this:
1> For initial order create, since it will be called by a RFC user (we use XI to pass the IDOC to R/3), I can check in the reqmnt that user type should not be RFC user type and hence reqmnt will not be met and no order conf will be sent. Order will be created with order rejection code for each line.
2> Order is created , end user reviews the order, if all is OK, removes the order rejection code from each line, saves the order, order req is called at the header, user type is a on-line user, reads all line items fron VBAP into XVBAP and ur logic is read and reqmnt is met and order conf is sent.
If for any reason order is saved and order rejection code is not removed from ALL line items, reqmnt is not met and order o/p is NOT triggered.
IF order is saved and there is atleast one line item without any blocks, reqmnt is met, order conf IDOC is triggered and in IDOc user exit, items with order reason codes are rejected/deleted from XVBAP table and order conf is sent only for line items without any bocks.
It should hopefully work. I will let you know.
I know, you do not care abt the entire solution / story, but it helps to validate my solution and maybe it will be useful for someone who is trying to acheive the same solution.
Thanks Again.
