Creating and changing a production order from ABAP
Creating production orders is one of common tasks when you have some external system that does the planning. Even if you work “directly” in R/3, you will probably need to create or change production orders. The SAP’s standard answer - BDC - is not really performant if you are processing a lot of data. To disappointment of any ABAPer, SAP provides no BAPIs to deal with that task (they do for order confirmations though). But fortunately, there are some other function modules that can help us. Before going further, I have to say that those functions can help you to create a production order, change its header parameters like scheduled start, or change its operations. Changing components, documents or production resources still has to be done with BDC (CO01 or CO02).
For production orders, SAP has implemented an interface for external planning systems (and even provided some documentation!). Their own “external” system, APO, does not use those functions (actually, one function supporting different tasks), but they are kind of official and you can find some documents on them in SAP help. Of course, the use is not limited to external systems and the function can be used directly from ABAP programs.
So, let’s start with creating an order. The function that we are going to use is CLOI_CHANGES_UPL_31. Don’t get confused by the “31″ in its name. It works perfectly in 4.6 and (most likely) in later version of R/3. There is one inportant point that you have to keep in mind when working with the function: you are given just one call per session. That means, you can create one order or many orders, but with one call. After that, some internal state data is messed up and to save us from initializing it (which has to be done with some really internal functions), we better start a new sesion if we need to call the function again. So, in my example code below I am going to check whether the current session is not the last one allowed for the current user and call the function in a new task. Note that we have to do the check before EACH call unless we are really sure (I do it only once in the sample code below). Since it’s going to be an anynchronous call, we need to suspend our program until the function running in parallel finishes and get the return data into our program. This is achieved with standard SAP constructs like “performing … on end of task” in the CALL FUNCTION statement and “receive results” in the form that is performed. I am also using a global variable that tells me that the call is over. You can find more useful information in SAP OSS note 545860 that described those specifics about calling that function.

endform.
The list of created production orders is returned back in the global table t_cloi_ord_exp. Now, let’s release them. (Setting, for example, technically complete status is similar). We are going to use the parameter cloi_ordu_imp instead of cloi_ordi_imp (I for insert, U for update). We populate the field FIELD with the value “METHOD” to say that we are not setting any values but we want to call a “method” of releasing the order (method in the same sense as in object programming).
* release created prod order
clear: lt_cloi_ordu.
loop at t_cloi_ord_exp into lw_cloi_ord_exp.
check not lw_cloi_ord_exp-aufnr is initial.

Now, as the order is created and released, let’s do some simple change. We are going to change the workcenter of the order’s operation.

append lw_cloi_ord_opru to lt_cloi_ord_opru.
clear: lt_cloi_methods_exp, t_cloi_messages_exp,

call function 'CLOI_CHANGES_UPL_31'

cloi_method_log_exp = lt_cloi_methods_exp
cloi_message_log_exp = t_cloi_messages_exp
cloi_msg_obj_log_exp = lt_cloi_msg_obj_log_exp
cloi_ord_exp = t_cloi_ord_exp.
wait until f_flag = 'X'.
That’s it! The function that we use doesn’t let us do anything we may need, but it can be very useful anyways. It’s stable and “blessed” by SAP, and I have seen it used in third-party products that need to be integrated with SAP. If you have any doubts, or your supervisor does, don’t forget to point to the SAP help documentation. It’s a small reassurance that it’s not one of those “internal only” functions that are better to avoid. And, the main point will of course be the performance if compared with BDC.
