• What is the cause and solution for SAP error message FDC_POSTING_001161 - Tax calculation and manual tax only with net amounts possible ?

  The SAP error message FDC_POSTING_001161 indicates that there is an issue with tax calculation in the context of financial document posting. Specifically, it suggests that tax calculation and manual tax entries can only be performed when net amounts are used. This typically occurs in scenarios where the system expects net amounts for tax calculations but is receiving gross amounts or other configurations that do not align with the expected input.
  Cause:
  
  Gross vs. Net Amounts: The error often arises when the system is configured to expect net amounts for tax calculations, but the transaction is being processed with gross amounts.
  Configuration Issues: There may be settings in the tax configuration that dictate how taxes should be calculated (e.g., whether to use net or gross amounts).
  Document Type Settings: The document type being used may have specific settings that require net amounts for tax calculations.
  Tax Code Issues: The tax code used in the transaction may not be compatible with the current settings or may not be set up correctly.
  
  Solution:
  
  Check Amount Types: Ensure that the amounts being posted are net amounts if the system is configured to require them. If you are using gross amounts, consider adjusting the transaction to use net amounts instead.
  Review Tax Configuration: Go to the tax configuration settings in SAP (Transaction Code: OBYZ or similar) and verify that the settings align with your business requirements. Ensure that the tax calculation method is set correctly.
  Document Type Review: Check the settings for the document type being used in the transaction (Transaction Code: OBA7) to ensure it allows for the type of tax calculation you are attempting.
  Tax Code Validation: Verify that the tax code used is correctly configured and compatible with the transaction type. You can check this in the tax code configuration (Transaction Code: FTXP).
  Consult Documentation: Review SAP documentation or help resources for specific guidance on the error message and related configurations.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on tax calculation issues.
  Transaction Codes: Familiarize yourself with transaction codes related to tax configuration (e.g., OBYZ, FTXP, OBA7) to facilitate troubleshooting.
  User Roles and Authorizations: Ensure that the user performing the transaction has the necessary authorizations to post documents with tax calculations.
  
  If the issue persists after checking these areas, it may be beneficial to consult with your SAP support team or a functional consultant who specializes in financial accounting and tax configurations.
