  The SAP error message DDLS175 indicates that there is a mismatch in the type properties of a column in a database table or view definition. This error typically occurs during the Data Definition Language (DDL) operations, such as when you are trying to create or modify a table or view in the ABAP Dictionary.
  Cause:
  The error message DDLS175 is triggered when:
  
  Data Type Mismatch: The data types of the columns being compared or defined do not match. For example, if one column is defined as CHAR and another as VARCHAR, or if there is a mismatch in length or decimal places.
  Incompatible Attributes: The attributes of the columns (like length, decimal places, or whether they are nullable) do not align with the expected definitions.
  Foreign Key Constraints: If you are trying to create a foreign key relationship, the data types of the foreign key column and the primary key column must match exactly.
  
  Solution:
  To resolve the DDLS175 error, you can take the following steps:
  
  
  Check Column Definitions: Review the definitions of the columns involved in the error message. Ensure that their data types, lengths, and attributes match.

  Review Foreign Key Relationships: If the error is related to foreign key constraints, ensure that the columns involved in the relationship have the same data type and attributes.
  
  
  Use Data Dictionary Tools: Utilize the ABAP Dictionary (transaction SE11) to check the definitions of the tables and views involved. You can also use the "Where-Used List" feature to see where the columns are being used.
