IDoc creation on save and change of production order

Question

I am looking for a way to create, and send if possible (if not I'll send with a batch job), on the save (creation and change) of production orders.  This will be a modified LOIPRO iDoc.  Currently we have a customer exit on the save of the production order but because it is before the save we must predict the number of the prod order.  This has worked but now we are creating one production order per line item in a sales order (automatically) so this is causing us to predict the same production order number twice.  We need a way to automatically create and send an iDoc for all production orders for given plants.  Right now the solution we are looking at is creating an output type and running through those output types a few times a day, sending them down to the Shop Floor system (proprietary system). 
Is there anything setup in SAP that we can utilize?

Hi Rick,
Follow the below sample steps for changing component quantity:
DATA:
    l_methods TYPE bapi_alm_order_method,
    it_boperations TYPE STANDARD TABLE OF  bapi_alm_order_operation_e WITH HEADER LINE,
    it_components TYPE STANDARD TABLE OF bapi_alm_order_component_e WITH HEADER LINE,
    it_components1 TYPE STANDARD TABLE OF bapi_alm_order_component WITH HEADER LINE.
1. Call BAPI :BAPI_ALM_ORDER_GET_DETAIL , it will give existing order component details.
CALL FUNCTION 'BAPI_ALM_ORDER_GET_DETAIL'
    EXPORTING
      number        = <production order number>
    TABLES
      et_operations = it_boperations
      et_components = it_components
      return        = it_bapiret2.
2. Move it_components to components table compatibel to BAPI "BAPI_ALM_ORDER_MAINTAIN".
LOOP AT it_components.
MOVE-CORRESPONDING it_components TO it_components1.
_*"Note here while moving change the component quantity"*_
APPEND it_components1.
CLEAR it_components1.
ENDLOOP.
3. Build the methods table for change production order :
it_methods-refnumber = v_refnumber.
            it_methods-objecttype = 'COMPONENT'.
            it_methods-method = 'CHANGE'.
            it_methods-objectkey = v_objectkey.
            APPEND it_methods.
"Note v_refnumber has 1 to 1 relation ship with the components table, if you want to change First component in it_components1 then you have to enter value '1' here for v_refnumber.
it_methods-method = 'SAVE'.
        APPEND it_methods.
4 . Call
CALL FUNCTION 'BAPI_ALM_ORDER_MAINTAIN'
          TABLES
            it_methods   = it_methods
            it_component = it_components1
            return       = it_bapiret2.
  CALL FUNCTION 'BAPI_TRANSACTION_COMMIT'.
