Understanding Setup for Withholding for Security Services
To process withholding taxes for security services:
- In the Document Types (00/DT) and Document Types - Vouchers Only (00/DV) UDC tables, set up $P as the document type that identifies withholdings for security services. 
- Enter 2 in the Special Handling Code field of the values that you establish in the SUSS Withholding Concept (76/11) UDC table to identify the SUSS withholding concept for investigation and security services. 
- Set up a payment instrument in the Payment Instrument (00/PY) UDC table for taxes for security services that you withhold from suppliers. - Specify in the fifth and sixth positions of the Special Handling Code field whether withholding applies and is accumulated. - Use position five to enter Y (yes) or N (no) for application of the withholding tax, and use position six to enter Y (yes) or N (no) to specify whether the system accumulates the withholding taxes in the F76A0456 table. The system treats blank values in the fifth and sixth positions as Y. 
- Verify that other system setup, such as AAIs, next numbers, UDCs and so on, are set up for the withholding of taxes for security services. 
- Add values for the withholding of taxes on security services to: - S.U.S.S. W/H - Percentages (P760410A). 
- S.U.S.S. W/H - Exempt Percentages (P760416A).
