• What is the cause and solution for SAP error message MC155 - Text table & does not have a language key field ?

  The SAP error message MC155 indicates that there is an issue with a text table that is expected to have a language key field, but it does not. This typically occurs in the context of SAP's Material Management (MM) or other modules where text tables are used to store descriptions or other language-dependent information.
  Cause:
  The error arises when:
  
  A text table is defined in the system without a language key field (usually SPRSL).
  The system is trying to access or manipulate this text table, expecting it to have a language key for proper localization and translation handling.
  The table may have been incorrectly configured or modified, leading to the absence of the required language key.
  
  Solution:
  To resolve the MC155 error, you can take the following steps:
  
  
  Check Table Definition:
  
  Use transaction SE11 (Data Dictionary) to check the definition of the text table that is causing the error.
  Ensure that the language key field (SPRSL) is included in the table definition.
  
  
  
  Modify Table Structure:
  
  If the language key field is missing, you may need to modify the table structure to add it. This typically requires appropriate authorizations and should be done with caution, as it can affect existing data and functionality.
  Use transaction SE14 (Database Utility) to adjust the table structure if necessary.
  
  
  
  Review Custom Code:
  
  If there is custom code or enhancements that interact with this text table, review them to ensure they are correctly handling the language key.
  Make sure that any SELECT statements or data manipulations account for the language key.
  
  
  
  Transport Requests:
  
  If changes are made to the table structure, ensure that they are included in a transport request for proper deployment across different environments (e.g., development to production).
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to the specific module you are working with for any additional guidance or known issues.
  
  
  
  Testing:
  
  After making changes, thoroughly test the functionality to ensure that the error is resolved and that the text table behaves as expected.
