How To Fix AD066 - Output length for data type & is set to &

SAP Error Message - Details

• Message type: E = Error

• Message class: AD - Data Dictionary application messages

• Message number: 066

• Message text: Output length for data type & is set to &

What causes this issue?

Some data types have a fixed length. For example, the date
always consists of 8 characters, that is, data type DATS is
stored as char(8). The output length is calculated from the
length of the data type and the required number of formatting
characters and, thus, also has a fixed length. For example, the
output length of DATS is fixed at 10 (8 figures plus two periods
to separate the year from the month and the month from the day).
You have specified an output length different from the
fixed output length for the data type you have selected.

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

System Response

The system sets the correct output length automatically and issues a
message.

How to fix this error?

No action required. You may need to check whether you have selected the
correct data type. You can obtain an overview of allowed data types by
pressing the F4 key on the <LS>data type</> field.

• What is the cause and solution for SAP error message AD066 - Output length for data type & is set to & ?

  The SAP error message AD066 typically indicates that there is a mismatch between the output length defined for a data type and the actual length of the data being processed. This error often arises in the context of ABAP programming, particularly when dealing with data types in structures or tables.
  Cause:
  The error message AD066 occurs when:
  
  The output length for a specific data type is set to a value that does not match the actual length of the data being processed.
  This can happen if the data type is defined incorrectly in the ABAP Dictionary (SE11) or if there is a mismatch in the data being passed to a function module or method.
  
  Solution:
  To resolve the AD066 error, you can take the following steps:
  
  
  Check Data Type Definition:
  
  Go to transaction SE11 (Data Dictionary) and check the definition of the data type mentioned in the error message.
  Ensure that the output length is correctly defined according to the expected data.
  
  
  
  Review ABAP Code:
  
  If the error occurs in a specific ABAP program, review the code to ensure that the data being assigned to the variable matches the defined length of the data type.
  Look for any implicit or explicit type conversions that might be causing the mismatch.
  
  
  
  Adjust Output Length:
  
  If necessary, adjust the output length of the data type in the ABAP Dictionary to match the actual data length being processed.
  
  
  
  Check Function Module/Method Parameters:
  
  If the error occurs when calling a function module or method, check the parameters being passed to ensure they conform to the expected data types and lengths.
  
  
  
  Testing:
  
  After making changes, test the program or function to ensure that the error is resolved.
  
  
  
  Related Information:
  
  Transaction Codes: SE11 (Data Dictionary), SE80 (Object Navigator), SE37 (Function Module).
  ABAP Data Types: Understand the different data types in ABAP (CHAR, NUMC, DATS, etc.) and their respective lengths.
  Debugging: Use the ABAP debugger to step through the code and identify where the mismatch occurs.
  SAP Notes: Check for any relevant SAP Notes that may address specific issues related to this error message.
  
  By following these steps, you should be able to identify and resolve the cause of the AD066 error in your SAP environment.
