Repeat output automatically in changes sales order

Question

HI all,
  I need to resend an output ZEDI whenever  the sales order is CHANGED based on customer number, change in quantity, price and rejection code.   The ZEDI output is created when the order is saved.  My thinking is that i would need to write a requirement for this.   The ZEDI is using requirement 2 now. However, i am going to create a new requirement, put those codes from reqmnt 2 and apply to the new requirement.   Do you have any suggestions how i can check the changes for  quantity changes, price changes and rejection code ?  Will it work with the new requirement ?
thanks
Joyce

In a requirement, to allow the output proposal, set SY-SUBRC = 0.  To stop the output proposal,  set SY-SUBRC = 4.  In your case, the best approach is to set SY-SUBRC = 4 until you find a condition that should trigger the output, then set SY-SUBRC = 0.  Be aware of DB selections and other actions that change the value of SY-SUBRC or use a local variable to assign the value at the end of the routine (see examples in your system).
For price changes, the easiest way is to analyze a net value change or a subtotal field change, rather than trying to access individual conditions.
Here is a field symbol usage example for sales order items (you need to do this for XVBAP and YVBAP in change mode (T180-TRTYP = 'V'), then loop/compare the items:
  DATA : lv_fieldname  TYPE fieldname.
  DATA : lt_xvbap TYPE STANDARD TABLE OF vbapvb,
         ls_xvbap TYPE vbapvb.
  FIELD-SYMBOLS: <fs_xvbap> TYPE ANY.
  lv_fieldname = '(SAPMV45A)XVBAP[]'.
* Get the Order Items
  ASSIGN (lv_fieldname) TO <fs_xvbap>.
  IF sy-subrc EQ 0.
    lt_xvbap = <fs_xvbap>.
  ENDIF.
