How To Fix IH666 - Structure & is too wide for downloading to MS Access (max. 2048 charact.)

IH666 - Overview

• Message type: E = Error

• Message class: IH - structuring

• Message number: 666

• Message text: Structure & is too wide for downloading to MS Access (max. 2048 charact.)

What causes this issue?

You have tried to export a list to MS Access.
You can only export tables with a maximum width of 2048 characters to
MS Access. For technical reasons, only the entire structure can be
exported even if you have not selected all the fields.
If a structure contains more than 2048 characters when you try to
download (for example, because customer-specific fields have been
added), you cannot export the data to MS Access.

System Response

The data cannot be downloaded to MS Access.

How to fix this error?

If possible, export the list to MS Excel as only selected columns are
exported.

Procedure for System Administrators

The structure you want to export cannot exceed 2048 characters. Note
that some fields require more characters when they are converted than
when they are saved internally (for example, separators are added
between day, month and year for data fields).

IH666 - Details

• The SAP error message IH666 indicates that a structure you are trying to download to Microsoft Access exceeds the maximum character limit of 2048 characters. This typically occurs when you are attempting to export data from SAP to Access, and the data structure or record length is too large for Access to handle.
  
  Cause:
  
  Data Structure Size: The structure you are trying to download contains fields that, when combined, exceed the 2048 character limit.
  Field Lengths: Individual fields within the structure may have large lengths, contributing to the overall size.
  Complex Data Types: If the structure includes complex data types or multiple concatenated fields, it can quickly exceed the limit.
  
  
  Solution:
  
  Reduce Field Lengths: Review the fields in the structure and see if any can be shortened or if unnecessary fields can be excluded from the download.
  Split the Data: If possible, split the data into multiple smaller structures or tables that can be downloaded separately.
