How To Fix MDG_OITC_CUST001 - Output length exceeds input length for field &1, key structure &2

SAP Error Message - Details

• Message type: E = Error

• Message class: MDG_OITC_CUST - MDG. Object Identifier Type Code messages

• Message number: 001

• Message text: Output length exceeds input length for field &1, key structure &2

What causes this issue?

The &V2& key structure, which is assigned to the &V3&
<DS:GLOS.4A798A2196154E79E10000000A421945>Object Identifier Type</> and
which belongs to the &V4&
<DS:GLOS.36AC9718927D42B9E10000009B38F982>Object Type</> consists of two
or more key fields. The output length of field &V1& is greater than its
internal length.
Object Identifier Type &V3& belongs to an Object Type &V4&, which is
enabled for <DS:GLOS.4B054D3963A24E75E10000000A421945>key mapping</>.
For key mapping to work, you must ensure that the output length defined
for each key component within an <LS>Object Identifier Type</> is less
than or equal to the internal field length, or you must explicitly
define a delimiter for the &V2& key structure.
A delimiter is required if the external format of the data for the key
field is longer than the internal format of the data for the key field.
For example, a Universal Unique Identifier (UUID) can have an internal
field length of 16 and an output length of 32. If no delimiter is
defined, the concatenated key includes a truncated UUID with just 16
characters.

System Response

The system cannot store the record.

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

How to fix this error?

Choose from the following actions:
Change key structure &V2& so that the internal length of all fields is
at least equal to the output length.
Define a delimiter for key structure &V2&. Ensure this delimiter is not
a regular character within any of the key fields.

• What is the cause and solution for SAP error message MDG_OITC_CUST001 - Output length exceeds input length for field &1, key structure &2 ?

  The SAP error message MDG_OITC_CUST001 indicates that there is a mismatch between the output length and the input length for a specific field in the key structure of the Master Data Governance (MDG) system. This typically occurs during data processing or data transfer operations, where the system expects a certain length for a field but receives data that exceeds this length.
  Cause:
  
  Field Length Mismatch: The most common cause of this error is that the data being processed has a length that exceeds the defined length for the corresponding field in the data model or database table.
  Data Mapping Issues: If there are issues in the mapping of data from one structure to another (e.g., during data import or transformation), it can lead to this error.
  Custom Enhancements: If there are custom fields or enhancements in the MDG system that have different lengths than expected, this can also trigger the error.
  
  Solution:
  
  Check Field Definitions: Review the field definitions in the data model to ensure that the lengths are correctly defined. Compare the lengths of the fields in the source data with those in the target structure.
  Data Validation: Before processing the data, validate the input data to ensure that it conforms to the expected lengths. This can be done through data cleansing or transformation processes.
  Adjust Data Mapping: If the error occurs during data transfer, check the mapping configuration to ensure that the data is being mapped correctly and that the lengths are compatible.
  Modify Field Lengths: If necessary, consider modifying the field lengths in the data model to accommodate the incoming data, but be cautious as this may have implications for other parts of the system.
  Debugging: If the issue persists, use debugging tools to trace the data flow and identify where the length mismatch occurs.
  
  Related Information:
  
  Transaction Codes: You may want to use transaction codes like MDGIMG to access the MDG configuration settings or SE11 to check the data dictionary for field definitions.
  SAP Notes: Check for any relevant SAP Notes that may address known issues related to this error message.
  Documentation: Review the MDG documentation for guidelines on data modeling and field length specifications.
  Community Forums: Consider searching or posting in SAP community forums for additional insights or similar experiences from other users.
  
  By following these steps, you should be able to identify the root cause of the error and implement a suitable solution.
