Figure below presents only the "normal" horizontal flows for the PtoP process. In other words, that figure intentionally ignores flows related to exception routines.
REQUIRED: Using given Figure as the model, create a figure that shows all the horizontal data flows related to handling purchase returns to vendors. Observe the following specific requirements:
a. At the top of the figure, draw triangles to show the functional entities involved in processing purchase returns. Enter the titles of the specific managers that are involved, including any new managers not shown in given Figure.
b. Near the right margin, draw a vertical line to demarcate the PtoP process from the "environment." As you draw the horizontal flows, insert any necessary external entities to the right of the vertical line.
c. Draw all of the horizontal flow lines (and their directions) needed to process purchase returns. Number each flow, starting with 1.
d. List the numbers 1 . . . n to correspond to each flow line added to the diagram in part (c). Provide a brief description of each information flow number.
