What causes this issue?

A minimum length of 256 is assumed for the data type specified for the
domain. This data type should, therefore, only be used for long fields.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message AD728 - Minimum length & is assumed for data type & ?

  The SAP error message AD728 typically indicates that there is a problem with the length of a data type in your ABAP program or data dictionary. Specifically, it suggests that the minimum length for a certain data type is not being met. This can occur in various contexts, such as when defining fields in a database table, structures, or when using certain data types in your ABAP code.
  Cause:
  
  Data Type Definition: The data type being used has a minimum length requirement that is not being satisfied. For example, if you are using a character type (like CHAR) and the length defined is less than the minimum required length.
  Field Length in Database Tables: If you are trying to insert or update a record in a database table and the field length is shorter than what is defined in the data dictionary.
  Parameter Length in Function Modules: If you are calling a function module and passing parameters that do not meet the required length.
  
  Solution:
  
  Check Data Type Definitions: Review the data type definitions in your ABAP program or data dictionary. Ensure that the lengths of the fields or variables meet the minimum length requirements.
  Adjust Field Lengths: If you are defining a field in a database table or structure, make sure that the length is set appropriately. For example, if a CHAR field requires a minimum length of 1, ensure that it is defined as such.
  Modify Function Module Parameters: If the error occurs when calling a function module, check the parameters being passed and ensure they meet the required lengths.
  Use Appropriate Data Types: If you are using a data type that has a minimum length requirement, consider using a different data type that fits your needs without violating the length constraints.
  
  Related Information:
  
  SAP Documentation: Refer to the SAP Help Portal or the ABAP documentation for detailed information on data types and their length requirements.
  Data Dictionary (SE11): Use transaction SE11 to check the definitions of database tables and structures to ensure that field lengths are correctly defined.
  ABAP Editor (SE38): Use transaction SE38 to edit your ABAP programs and make necessary adjustments to data type definitions or variable declarations.
  
  By addressing the length requirements as indicated by the error message, you should be able to resolve the issue. If the problem persists, consider checking for any additional constraints or dependencies that may be affecting the data type in question.
