• What is the cause and solution for SAP error message /ISIDEX/EDEREG_INV121 - Billing period implausible; no delivery or only partial delivery ?

  The SAP error message /ISIDEX/EDEREG_INV121 indicates that there is an issue with the billing period in relation to deliveries. Specifically, it suggests that the billing period is implausible because there are either no deliveries or only partial deliveries associated with the billing document.
  Cause:
  
  No Deliveries: The billing document is created without any associated deliveries, which makes it impossible to generate a valid invoice.
  Partial Deliveries: If there are deliveries, they may not cover the entire billing period, leading to inconsistencies in the billing process.
  Incorrect Billing Period: The billing period specified in the billing document may not align with the delivery dates, causing the system to flag it as implausible.
  Configuration Issues: There may be configuration settings in the SAP system that are not aligned with the business processes, leading to this error.
  
  Solution:
  
  Check Deliveries: Verify if there are any deliveries associated with the billing document. If there are none, you may need to create the necessary deliveries before proceeding with billing.
  Review Partial Deliveries: If there are partial deliveries, ensure that they cover the billing period. You may need to adjust the billing document or create additional deliveries to cover the missing items.
  Adjust Billing Period: If the billing period is incorrect, adjust it to match the delivery dates. This can often be done in the billing document settings.
  Configuration Review: Check the configuration settings in the SAP system related to billing and delivery. Ensure that they are set up correctly to avoid such issues in the future.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on handling this error message.

  User Exits and BAdIs: If custom logic is implemented in your SAP system, review any user exits or BAdIs that might affect the billing and delivery process.
