How To Fix CNV_NCE_BAS141 - NR interval &1: function module name is not specified

SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_NCE_BAS - Number conversion engine: messages

• Message number: 141

• Message text: NR interval &1: function module name is not specified

What causes this issue?

You have maintained the rule 'External code' for the number range
interval, but have not provided the name of your conversion function
module.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Enter the name of your conversion function module into the field
'External function name'.

Procedure for System Administrators

The conversion function module should correspond to the predefined
template CNV_NCE_CONVERSION_TEMPLATE. If you have already created a
function module, check the compliance of its parameters with the
parameters of the template function module. If you have not yet created
your function module, call the transaction SE37, input the name of the
template function module into the corresponding field and press button
'Copy'. Save new function module under the desired name in your function
group. This way you make sure that the parameters of your function
module are equivalent to the parameters of CNV_NCE_CONVERSION_TEMPLATE.

• What is the cause and solution for SAP error message CNV_NCE_BAS141 - NR interval &1: function module name is not specified ?

  The SAP error message CNV_NCE_BAS141 with the description "NR interval &1: function module name is not specified" typically occurs in the context of data conversion or migration processes, particularly when using the SAP Conversion Tools or during the execution of a custom program that involves number ranges.
  Cause:
  This error usually indicates that there is a missing or incorrectly specified function module name in the configuration of a number range interval. The number range object is expected to have a function module associated with it, which is responsible for generating or managing the number ranges. If this function module is not specified, the system cannot proceed with the operation, leading to this error.
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Number Range Configuration:
  
  Go to transaction code SNRO (Number Range Objects).
  Find the relevant number range object that is causing the issue.
  Check the intervals defined for this number range object and ensure that a function module is specified for the relevant interval.
  
  
  
  Specify Function Module:
  
  If the function module is missing, you will need to specify it. This can usually be done in the configuration settings of the number range object.
  Ensure that the function module you specify is correctly implemented and can handle the operations required for the number range.
  
  
  
  Review Custom Code:
  
  If you are using custom code or enhancements, review the code to ensure that it correctly references the number range object and its associated function module.
  Make sure that any custom logic does not inadvertently omit the function module specification.
  
  
  
  Check for Transport Issues:
  
  If this error appeared after a transport, ensure that all necessary objects, including function modules and number range configurations, were transported correctly.
  
  
  
  Consult Documentation:
  
  Review any relevant SAP documentation or notes related to the specific number range object or the conversion process you are working with.
  
  
  
  Testing:
  
  After making the necessary changes, test the process again to ensure that the error is resolved.

  SAP Notes and Documentation:
  
  Check SAP Notes for any known issues or patches related to the specific number range object or conversion tools you are using.
  
  
  
  Debugging:
  
  If the issue persists, consider debugging the program or process that is triggering the error to identify where the function module name is expected but not provided.
  
  
  
  By following these steps, you should be able to identify and resolve the cause of the CNV_NCE_BAS141 error in your SAP system.
