• What is the cause and solution for SAP error message 0H454 - Indenting key fields is not allowed ?

  The SAP error message 0H454 ("Indenting key fields is not allowed") typically occurs in the context of SAP ABAP programming or when working with certain SAP transactions that involve data entry or report generation. This error indicates that there is an attempt to indent key fields in a report or a data structure where indentation is not permitted.
  Cause:
  
  Key Fields Indentation: The error arises when key fields (fields that uniquely identify a record in a database table) are indented in a report or a data structure. In SAP, key fields must be aligned to the left without any indentation.
  Incorrect Formatting: The formatting of the output or the structure definition may have been incorrectly set up, leading to the indentation of key fields.
  Report Layout Issues: If you are using a report layout (like Smart Forms or SAPscript), the layout might be incorrectly configured to indent key fields.
  
  Solution:
  
  Check Report Layout: If you are working with a report, check the layout settings to ensure that key fields are not indented. Adjust the layout to align key fields to the left.
  Modify Data Structure: If you are defining a data structure in ABAP, ensure that key fields are defined without any indentation. Review the structure definition in the ABAP Dictionary (SE11) or in the program code.
  Review Code: If you are writing custom ABAP code, ensure that you are not using indentation for key fields in your output statements (e.g., WRITE statements).
  Consult Documentation: Refer to SAP documentation or help resources for guidelines on formatting reports and data structures correctly.
