How To Fix CC146 - Field & requires length &, but field length is &

SAP Error Message - Details

• Message type: E = Error

• Message class: CC - ECM: Messages

• Message number: 146

• Message text: Field & requires length &, but field length is &

What causes this issue?

You want to do a date shift.
When you do a date shift, the valid-from date for all effectivity
periods of all linked objects is re-calculated by the system.
This changes the sequence of effectivity periods on &V1& for BOM &V2&,
item &V3&.

System Response

The system checks whether the BOM is still consistent. The BOM is not
consistent if, for example, the BOM has already been changed with a
change number with the same valid-from date as the new valid-from date
you define in your date shift.

How to fix this error?

Since your date shift violates the consistency of the BOM named above,
you cannot carry out the date shift.

• What is the cause and solution for SAP error message CC146 - Field & requires length &, but field length is & ?

  The SAP error message CC146 indicates that there is a mismatch between the expected length of a field and the actual length defined in the system. This error typically occurs in the context of data entry or data processing where a field is expected to have a certain length, but the data being processed does not conform to that length requirement.
  Cause:
  
  Field Length Mismatch: The primary cause of this error is that the data being entered or processed exceeds the defined length of the field in the database or data structure.
  Configuration Issues: There may be configuration settings in the SAP system that define the length of fields incorrectly.
  Data Import/Export Issues: If data is being imported from an external source, the source data may not conform to the expected field lengths.
  Custom Development: If there are custom programs or enhancements, they may not be handling field lengths correctly.
  
  Solution:
  
  Check Field Lengths: Review the field definitions in the relevant data structure (e.g., database table, data element) to ensure that the lengths are defined correctly.
  Data Validation: Ensure that the data being entered or processed conforms to the expected lengths. This may involve trimming excess characters or validating input before processing.
  Adjust Configuration: If the field lengths are incorrectly configured, adjust them in the relevant configuration settings.
  Review Custom Code: If there are custom programs or enhancements, review the code to ensure that it correctly handles field lengths and does not exceed the defined limits.
  Error Handling: Implement error handling in your programs to catch such issues before they cause runtime errors.
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes like SE11 (Data Dictionary) to check the definitions of the fields involved.
  Debugging: If the error occurs in a custom program, use the ABAP debugger to trace the execution and identify where the field length mismatch occurs.
  SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide additional guidance.
  Documentation: Review SAP documentation related to data structures and field definitions for best practices on defining and using fields.
  
  By addressing the root cause of the field length mismatch and ensuring that data conforms to the expected formats, you can resolve the CC146 error effectively.
