The SAP error message FIRU_VAT014 indicates that a specific parameter (denoted as &1) is not allowed in Sales and Distribution (SD) documents. Instead, the system is instructing users to use header texts for the relevant information. This error typically arises in the context of VAT (Value Added Tax) processing within the SD module.
Cause: Incorrect Parameter Usage: The error is triggered when a parameter that is not permitted in the context of SD documents is being used. This could be due to a configuration issue or an attempt to input data in a field that is not designed to accept it. Document Type Restrictions: Certain document types in SD may have restrictions on what can be entered in specific fields, particularly those related to tax information. Custom Development: If there are custom developments or enhancements in the system, they may inadvertently lead to this error if they do not comply with standard SAP rules.
