  The SAP error message RAT201 indicates that there is a problem with the pro-rata VAT calculation due to a missing entry in the RAT_COEF table for the specified key date. This error typically arises in the context of VAT (Value Added Tax) calculations, particularly when dealing with pro-rata adjustments for input tax.
  Cause:
  The error message RAT201 is triggered when the system attempts to calculate pro-rata VAT but cannot find the necessary coefficient (RAT_COEF) for the specified key. The key consists of three components (usually related to the company code, tax type, and tax jurisdiction) and the key date is the date for which the VAT calculation is being performed.
