• What is the cause and solution for SAP error message DDLS346 - CAST & from & to type &: target type length too small, loss of data poss. ?

  The SAP error message DDLS346 indicates that there is a potential data loss when trying to cast or convert data from one type to another due to the target type's length being too small. This typically occurs during data type conversions in ABAP programs or when working with database tables and fields.
  Cause:
  The error arises when:
  
  You are trying to assign a value from a source data type to a target data type that has a smaller length or precision.
  For example, if you are trying to assign a string of 10 characters to a field that can only hold 5 characters, the system raises this warning because it could lead to truncation of data.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Data Types: Review the data types of the source and target fields. Ensure that the target field has sufficient length to accommodate the data from the source field.
  
  
  Modify Target Field: If possible, increase the length of the target field in the database table or structure to match or exceed the length of the source field.
  
  
  Data Truncation Handling: If you cannot change the target field's length, consider implementing logic to handle potential data truncation. This could involve:
  
  Trimming the source data before assignment.
  Using a different data type that can accommodate the data without loss.
  
  
  
  Use of CAST: If you are using a CAST operation, ensure that the target type is appropriate for the data being cast. You may need to choose a different target type that can handle the data without loss.
  
  
  Review ABAP Code: If the error occurs in ABAP code, review the relevant code sections where the assignment or casting is taking place. Ensure that the data types are compatible.
  
  
  Related Information:
  
  Data Type Lengths: Familiarize yourself with the data types and their lengths in ABAP. Common types include CHAR, NUMC, DATS, TIMS, etc.
  Database Table Definitions: Check the definitions of the database tables involved to understand the lengths and types of fields.
  SAP Notes: Look for any relevant SAP Notes that might address specific issues related to this error message.
  Testing: After making changes, thoroughly test the application to ensure that the changes do not introduce new issues.
  
  By following these steps, you should be able to resolve the DDLS346 error and prevent potential data loss in your SAP applications.
