AY155 - Details

• The SAP error message AY155 ("Selected value was not adopted") typically occurs in the context of asset accounting or when dealing with asset master data. This error indicates that the system could not adopt or accept the selected value for a particular field or parameter during a transaction or process.
  Causes:
  
  Inconsistent Data: The selected value may not be consistent with the existing data in the system. For example, if you are trying to assign a value that does not exist in the master data or is not valid for the current context.
  Field Restrictions: Certain fields may have restrictions or dependencies that prevent the adoption of the selected value. For instance, if a field is mandatory and the selected value does not meet the criteria.
  Authorization Issues: The user may not have the necessary authorizations to make changes to the selected value.
  
  Configuration Issues: There may be configuration settings in the asset accounting module
