STATUS_READ & line item rejection reason - too complex

Question

Hi All,
  I have to trigger an output to a smartform via an output routine. I have to do the following checks in my output routine before I decide to propose the output or decline to propose the output if conditions fail.
1. Order header can have status PEND, Hold, Release. IF the status has changed to anything else except pending, i should propose output.
2. Again if a line item is rejected with certain reason code, then also I have to propose the output.
  Both the above conditions must be checked before proposing the output. My issue is how do I know what was the old value of status and rejection reason.
I tried using FM STATUS_READ, but it does not give something like this was the old value and this is the new value. I do not find any FM to get item rejection reason. Do I have to use change documents for these.
examples
a)Order with 2 Framing Configurable Line Items.  The user status of the order is changed from PEND to QAHD.  The standard order output label is proposed for both line items on the order.  At a later time, one of the line items is rejected for reason 90 (for example).  At that time a new label is created, just for that specific line item – with the rejected artwork text on the label. 
  In this case if I use STATUS_READ, i will get active status as QAHD, so I will try to propose normal output so I am fine. Later when the item is rejected, I will again get staus as QAHD and I will propose output for one unrejected item which is WRONG. I had already proposed the output in past, so I should not. I should only propose output for the rejected item.
b)Order with 2 Framing Configurable Line Items.  The user status of the order is still in a PEND status.  The user changes one of the line items to a rejected for reason 91 (for example).  A label is printed just for that line item with the rejected artwork text on the label.  At a later time, the user status on the order is changed from PEND to QARD.  A label will print, only for the unrejected line item and the label is the standard order output label for HJ.
  In this case I do not know where to get the old rejection reason of item. If I do a database select, I will get current rejection reason 91, but how do I know if I had already proposed the output or not for a certain item.
c)Another scenario to think about is that there is nothing preventing the user from setting a rejection status on an item and changing the user status at the same time and saving it.  In that case we would want only one label per piece (the rejected label for the rejected item and the standard label for the non-rejected item).
  I think I have to check the time order was updated and do something like that.
All inputs are welcomed.

Answer 1

Write the code like
  concatenate 'OR' int_orders-aufnr into d_objnr.
    call function 'STATUS_READ'
         EXPORTING
              client          = sy-mandt
              objnr           = d_objnr
         TABLES
              status          = t_status
         EXCEPTIONS
              object_not_found.
Read table t_status with key stat = 'I0076'.
if sy-subrc eq 0.
do not print output.
endif.
