1. Open the Configuration Activity “Define Currency Settings for Ledgers and Company Codes”(SSCUI ID: 103379) 
2. Attempt to enable “Company Code Specific Conversion” for currency type 10, but this field is gray for some of the currency types, for example, currency type 10 (Company Code Currency), currency type 00(Document Currency) and you can’t change it. Fields in white are changeable. 
   
   

Company Code Specific Conversion: Definition level for the currency type settings that determines whether the currency type is to be used for all company codes (when the box isn’t checked) or can be selected for particular company codes (when the box is checked). 

The "Company Code Specific Conversion" field appears grayed out for currency type 10, indicating that the standard system setting is fixed and unchangeable . This is because currency type 10 represents the local currency of the company code, which is automatically determined based on the country where the company code is created and serves as the foundation-level element in company code definition.

 The company code currency conversion settings are managed globally rather than at the company code level, as this currency type serves as the base reference for all financial postings within that company code. Only user-defined currency types (starting with Y or Z) and certain other standard currency types allow the "Company Code Specific Conversion" setting to be modified.

Do not attempt to enable “Company Code Specific Conversion” for currency type 10, as this is not supported in Public Cloud.
