Modify Automaticaly order position on IS-MILL solutions.

Question

Hi. First, excuse me for my poor english. I'm not use it normally.
We have MILL package installed on our systems because we need to make productions orders with various positions.
But we need to automate the process that create, modify and/or delete positions on a order.
We try to do this with CALL TRANSACTIONS to CO02 transaction, but the logic flow control of this, is too much complex and almost always a message appear or sometimes a screen appear (normally settlement rules) or simply, the changes are not made.
We need a bapi, function module, class, etc that help us to make this, create, change and/or delete positions.
We probe with class CL_MILL_IT_ORDER and CL_MILL_IT_ORDERPOS but the changes are not made, and the BAPI _PRODORD* not work with MILL orders.
Has anyone do something like this or can tell me how can i do this?
Thanks.

Answer 1

Use batch input.  It is complex but it seems to be the only way.  I used it to create the upload production order with mutliple order items in creation mode.  Never use it in change mode though.  The BAPI won't help since it is not provided the data for order item or components.
For the class, I never used these two classes and there is no documentation about it so I can't comment much.  It seems to be linked with standard program of Mill to calculate the settlement rule by weight (settlement rule PP5).
