# Construct SAP Goods Receipt XML with Conditional Segments
Transform warehouse goods receipt JSON into a multi-segment SAP RFC XML. You will practice using conditional logic to include batch segments only when present, applying unit-of-measure conversions via a lookup variable (`vars.uomLookup`), and leveraging advanced DataWeave selectors (like the filter `[?()]` and key present `?` operators) to construct dynamic XML structures with varying repeating elements.
