  SAP Error Message: WG231 - Collective numbers cannot be specified
  
  Cause:
  The error WG231 occurs when you try to enter or use collective numbers (also known as group numbers or batch numbers) in a context where the system does not allow it. Specifically, this happens in processes or transactions where individual document or item numbers must be used instead of collective or group numbers.
  In SAP, collective numbers are used to group several documents or items under a single number for processing convenience. However, certain transactions or functions require unique, individual numbers for each document or item to ensure proper tracking and processing.
  Typical scenarios include:
  
  Attempting to post or process goods movements, invoices, or deliveries where the system expects individual document numbers.
  Using collective numbers in transactions or reports that do not support them.
  Configuration settings or master data that restrict the use of collective numbers in certain processes.
  
  
  Solution:
  To resolve the WG231 error, consider the following steps:
  
  
  Check the Transaction or Process:
  
  Verify if the transaction you are using supports collective numbers.
  If not, use individual document or item numbers instead of collective numbers.
  
  
  
  Review Input Data:
  
  Ensure that you are not entering collective numbers where individual numbers are required.
  If you have a list of documents or items, process them individually or in a way supported by the transaction.
  
  
  
  Configuration Settings:
  
  Check if there are any settings in the customizing (SPRO) related to the use of collective numbers for the specific process.
  For example, in Inventory Management or Billing, certain settings might restrict collective number usage.
  
  
  
  Master Data and Number Ranges:
  
  Verify if the number ranges assigned to the documents allow collective numbers.
  Adjust number range settings if necessary, but only if it aligns with business requirements.
  
  
  
  Consult Documentation or SAP Notes:
  
  Look for SAP Notes related to WG231 for any patches or specific instructions.
  Sometimes, the error might be due to a known issue fixed in a support package.
