How To Fix EA358 - Field &1: External length &2 greater than &3 for appl. data element &4

EA358 - Overview

• Message type: E = Error

• Message class: EA - IDoc Basis Messages

• Message number: 358

• Message text: Field &1: External length &2 greater than &3 for appl. data element &4

What causes this issue?

The format of field '&v1&' may be incorrect. For external
representation of a field, an ABAP data type is converted into a text
field. The external text field must have a minimum length so that a
loss-free transfer is possible between the two fields.
The data element '&v4&' stated requires '&v3&' character places
externally. However, only '&v2&' character places are defined in the
repository structure.

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?

Please check whether there was a change in a domain or a data element
and whether the difference determined was caused by this.
Change the data element used or use another data element, as necessary.
If processing or application logic demonstrates that no format
violations arise, no change is required.
If external standards must be adhered to, it may be necessary to define
the external field longer than the internal. Ensure, however, that an
appropriate format conversion takes place in processing.

  The SAP error message EA358 indicates that there is a mismatch between the external length of a field and the maximum length defined for that field in the application data element. This typically occurs when data being processed exceeds the defined limits, which can happen during data uploads, interface processing, or when data is being transferred between systems.
  
  Cause:
  
  Data Length Exceeded: The external data being processed has a length that exceeds the maximum length defined for the corresponding field in the SAP data dictionary.
  Incorrect Data Mapping: If data is being transferred from an external system, the mapping of fields may not be correctly defined, leading to longer data being sent than what SAP can handle.
  
  Configuration Issues: There may be configuration issues in the data model or in the way the data is being handled in the application.
  
  
  Solution:
