DT182 - Details

• The SAP error message DT182 indicates that there is an attempt to switch on the NOT-NULL flag for a data type that is not permitted to have this flag set. Specifically, this error occurs when dealing with a SHORT RAWSTRING type in ABAP (Advanced Business Application Programming).
  
  Cause:
  The error arises because the SHORT RAWSTRING data type in SAP does not support the NOT-NULL attribute. In ABAP, the NOT-NULL flag is used to indicate that a field must always contain a value (i.e., it cannot be NULL). However, the SHORT RAWSTRING type is designed to hold binary data and does not allow for the NOT-NULL constraint.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Change Data Type: If you need to enforce a NOT-NULL constraint, consider changing the data type from SHORT RAWSTRING to a different type that supports NOT-NULL, such as STRING or a character type (like CHAR or VARCHAR) that
