• What is the cause and solution for SAP error message STOBJ146 - Key must be contiguous and start at the first position ?

  The SAP error message STOBJ146 ("Key must be contiguous and start at the first position") typically occurs when there is an issue with the way a key is defined or structured in a database table or a data structure in SAP. This error is often related to the use of key fields in a database table or an internal table where the key fields are not contiguous or do not start from the first position.
  Cause:
  
  Non-contiguous Key Fields: The key fields in the table or structure are not defined in a contiguous manner. For example, if you have a composite key, the fields that make up the key must be defined one after the other without any gaps.
  Incorrect Key Definition: The key might not start from the first position of the structure or table, which is a requirement in SAP.
  Data Structure Issues: If you are working with internal tables or structures, the key fields must be defined correctly in the ABAP Dictionary.
  
  Solution:
  
  Check Key Definition: Review the definition of the table or structure in the ABAP Dictionary (SE11). Ensure that all key fields are defined contiguously and start from the first position.
  Modify Key Fields: If you find that the key fields are not contiguous, you may need to modify the structure to ensure that they are defined correctly. This may involve rearranging the fields or changing their definitions.
  Recreate the Table/Structure: In some cases, it may be easier to recreate the table or structure with the correct key definitions rather than modifying an existing one.
  Check for Gaps: Ensure that there are no gaps between key fields. For example, if you have a key made up of fields A, B, and C, they should be defined as A, B, C without any other fields in between.
  Test Changes: After making changes, test the functionality to ensure that the error no longer occurs.
  
  Related Information:
  
  Transaction Codes: Use transaction code SE11 to access the Data Dictionary and check the table or structure definitions.
  ABAP Development: If you are developing ABAP programs, ensure that you are using the correct data types and structures when defining internal tables and their keys.
  Documentation: Refer to SAP documentation or help resources for more information on defining keys in database tables and structures.
  
  If the issue persists after following these steps, consider reaching out to your SAP Basis or ABAP development team for further assistance, as they may have additional insights based on your specific SAP environment and configuration.
