To create tax invoices in the system some customizing work has to be done. Here, the required activities are listed.

• Document type & number range: At least one document type should be defined as the tax invoice e.g. TI. A separate number range should be assigned to this document type. The tax invoice will be numbered by the standard numbering. But if each issuing business place should have its own number range then create for each business place a document type. The document type for tax invoice must be valid for customer accounts and for G/L accounts.

• Posting keys: The tax invoice programs RFIDKRTC and RFIDKRTCIB have default posting keys when executing. But if you wish own posting keys because of some other customizing settings like maintained field status by posting keys, then create own posting keys.

• SAPscript layout sets: If the delivered layout sets do not match your form of the tax invoice you can change them or copy them before modifying (recommended).
