Certificate Numbering 
Use
The Generic Withholding Tax Reporting program can assign the withholding tax certificate a number at the time that it prints them out.
This feature is only available in Extended Withholding Tax .
Features
The system offers you two different ways of numbering withholding tax certificates. You can generate a withholding tax certificate number whenever you enter a withholding tax item, which ensures that the withholding tax items are numbered in the order that you post them. You can use different numbers for each withholding tax type. For more information about this procedure, see Configuring Certificate Numbering for Withholding Tax .
The Generic Withholding Tax Reporting program takes a different approach. You do not assign the withholding tax items a number as you enter them. Instead, the program assigns each certificate a number itself.

Periodic Processing
When you execute the Generic Withholding Tax Reporting program, fill out the Numbering and Updating group box. Here, you can either enter the number range that you defined in Customizing, or you can specify the number of the first withholding tax certificate manually. The program numbers the certificates sequentially.
If you select Record Certificate Numbers, the program records the withholding tax certificate number in each withholding tax item.
