Capital goods refer to manufactured goods that are used in the production of other goods or services. They include buildings, machinery, tools, vehicles, and equipment. When procuring capital goods, only 50% of applicable taxes can be claimed as input tax credit in the first year, with the remaining 50% credited in subsequent years. The procurement process in SAP involves creating material and vendor masters, generating a purchase requisition and purchase order, receiving goods, posting invoices, and transferring the remaining tax credit in the second year. Key aspects like asset values, tax determinations, and account assignments must be properly configured.
