• What is the cause and solution for SAP error message >BAPI018 - Selection interval is not permitted for fields "&1" ?

  The SAP error message BAPI018 indicates that a selection interval is not permitted for certain fields in a BAPI (Business Application Programming Interface) call. This typically occurs when you are trying to use a selection interval (like a range of values) for a field that does not support it.
  Cause:
  
  Field Type: The field you are trying to use with a selection interval may be a single-value field or a field that does not allow ranges. For example, fields that are defined as "CHAR" or "NUMC" types may not support selection intervals.
  BAPI Definition: The BAPI you are calling may have specific requirements for the input parameters, and using a selection interval for certain fields may not be allowed as per the BAPI's definition.
  Incorrect Parameter Usage: You might be using the wrong parameter or structure for the BAPI call, leading to the error.
  
  Solution:
  
  Check Field Definition: Review the data dictionary (SE11) for the field in question to determine if it supports selection intervals. If it does not, you will need to provide a single value instead of a range.
  Review BAPI Documentation: Check the documentation for the specific BAPI you are using (you can find this in transaction SE37 or SE80). Look for the expected input parameters and their types.
  Modify Input Parameters: If the field does not support selection intervals, modify your input to provide a single value instead of a range. For example, instead of providing a range like from_value and to_value, just provide a single value.
  Error Handling: Implement error handling in your code to catch this specific error and provide a user-friendly message or alternative processing logic.
  
  Related Information:
  
  BAPI Documentation: Always refer to the official SAP documentation for the specific BAPI you are using to understand its parameters and constraints.
  SAP Notes: Check SAP Notes for any known issues or updates related to the BAPI you are using.
  Debugging: If you have access to the SAP system, you can use transaction SE37 to test the BAPI and see how it behaves with different input values.
  
  By following these steps, you should be able to resolve the BAPI018 error and successfully call the BAPI with the correct parameters.
