Short Description and Why It's Useful

Currently completed items on the Purchase Order detail page are not clearly distinguishable from pending items which doesn't allows users quickly identify which products are no longer outstanding. This feature is crucial for users dealing with large and complex POs. Hence,

• Written code to display completed items too on the POs detail page.
• Written a function and added few template items so as to clearly display total orders count, pending items count, and completed items count.
