Hi Glenn,
User Exit – Function module IDOC_INPUT_ORDERS
In the function module IDOC_INPUT_ORDERS, form call_va01_new_orders is performed wherein BDC data is built up for every screen required to post a sales order. User Exit ZXVEDU04 is performed at various stages during the built up of BDC data
XI tool translates the order into an intermediate document (IDOC) with message type ORDERS and IDOC type ORDERS01. Reaching into SAP, the function module IDOC_INPUT_ORDERS processes the IDOC and calls VA01 transaction with BDC data built out from IDOC data. Successfully processed IDOC posts a sales order, whereas a failed IDOC processing generates workitem for workflow processing.
At a high level, the IDOC processing executes in the following manner:
1. Interpret IDOC header segments and captures organizational, customer master and purchase
order header details. Performs user exits for each segment to process customizations to data
processing.
2. Interprets item level segments and captures item level details like material information. Again,
it performs user exits for each segment.
3. Sums up the order data and determines the posting criterion viz. creating order with reference
etc.
4. Builds up batch data communication sequence (BDC) with respect to the required screen
sequence of posting a sales order.
5. While building up the BDC data, system performs user exit to process customizations to BDC
data.
6. Calls transactions VA01 using the BDC data.
7. If the processing fails, an appropriate workitem is generated for workflow processing.
if you give me brief i can help you out more.
Thank you .
