The task is to extract key fields from customer documents (Purchase Order (PO) and Bill of
Material (BOM)), and align them so that each PO item is enriched with the correct technical
details. Begin with the customer's purchase order, which may include multiple items. Each item
is linked to its BOM via a Material Number.

For every item in the PO, extract the Material Number along with the basic item details:
Quantity, Description, and Delivery Date (Format: DD/MM/YYYY). Use the item's Material Number from the PO to find the BOM having the same Material Number (represented as 'ID'). From the matching BOM, extract
the part's 'Part Designation' and part dimension (length followed by unit, e.g., 1487mm).

The final output should contain as many lines as the number of items in the PO. Each line
should have: Material Number, Quantity, Description, Delivery Date (from PO), Part
Designation, part dimension (from BOM).

Also, extract the following header information from the PO: Order Date, Buyer, Sales Person,
Shipping Address, Payment Terms.
