• What is the cause and solution for SAP error message RSDA186 - Field '&1': Value range reduced from &2 to &3 whole number places ?

  The SAP error message RSDA186 indicates that the value range for a specific field has been reduced, which can occur in the context of data extraction or transformation processes, particularly when working with DataSources or InfoObjects in SAP BW (Business Warehouse).
  Cause:
  The error message typically arises when:
  
  Data Type Mismatch: The field in question has a defined data type or length that is incompatible with the data being processed. For example, if a field is defined as a numeric type with a certain number of digits, but the incoming data exceeds that limit, the system will reduce the value range.
  Changes in Data Model: If there have been changes to the data model (e.g., changes in the InfoObject definition), it can lead to discrepancies in how data is interpreted.
  Data Source Configuration: The configuration of the DataSource may not align with the actual data being extracted, leading to truncation or rounding of values.
  
  Solution:
  To resolve the RSDA186 error, consider the following steps:
  
  
  Check Field Definition: Review the definition of the field in the DataSource or InfoObject. Ensure that the data type and length are appropriate for the data being processed.
  
  Go to the DataSource or InfoObject in the SAP BW modeling tools and verify the field properties.
  
  
  
  Adjust Data Type/Length: If the field definition is too restrictive, you may need to adjust the data type or length to accommodate the incoming data. This may involve:
  
  Modifying the InfoObject to increase the length of the field.
  Changing the data type if necessary.
  
  
  
  Review Data Source Settings: Check the settings of the DataSource to ensure that it is configured correctly to handle the data being extracted. This includes:
  
  Verifying the extraction logic.
  Ensuring that any transformations applied to the data do not inadvertently reduce the value range.
  
  
  
  Data Cleansing: If the incoming data contains values that exceed the defined limits, consider implementing data cleansing processes to handle or filter out such values before they reach the DataSource.
  
  
  Testing: After making changes, perform tests to ensure that the error does not recur and that data is being processed correctly.
