Create these problems into an UML (Unified Modeling Language) diagram using Visio, Word or Power Point.

Problem 1: Invoice Creation

1. An invoice has to be created by the Accounts payable (AP) department. First step is to create the billing document in SAP and to check the order using the invoice by the AP Processor.
2. In creating this step the AP processor has to select the number of posted deliveries and then execute to produce the invoice data.
3. After that the invoice has to be posted in the system and the process chain may be checked again by checking the original quotation once again.
4. At this stage, the order fulfilment process is completed.

Problem 2: Modifying Order Data

1. In the case of order changes, work schedule changes or Malfunction/breakdown, the order data has to be modified by the Planning department.
2. In the next step, the Planning Manager evaluates the order (based on the order & order changes) and may either decide in case of changing to divide tasks to clerks/persons in charge (based on personnel availability), or in case of new to redesign the whole order by the Planning employees.
3. After his decision, the Planning Manager has to select a work schedule for both options. Then he has also to select a plant and decide on operations sequence (based on the work process).
4. At the stage of deciding on the operations sequence, he has to define the work process and the work place group at the same time.
5. Finally, the process ends with the order data being successfully modified.
