• What is the cause and solution for SAP error message /SAPAPO/OM_TS078 - Overflow during propagation calculation: Number too large ?

  The SAP error message /SAPAPO/OM_TS078 Overflow during propagation calculation: Number too large typically occurs in the context of Advanced Planning and Optimization (APO) when the system encounters a numerical value that exceeds the limits of what can be processed during a propagation calculation. This can happen in various scenarios, such as during demand planning, supply network planning, or when working with large datasets.
  Causes:
  
  Large Numerical Values: The most common cause is that the system is trying to process a number that is too large for the data type being used. This can happen with demand forecasts, supply quantities, or other numerical inputs.
  Data Type Limitations: The data types used in the calculations may have specific limits (e.g., integer overflow), and if the calculations exceed these limits, the error will occur.
  Incorrect Configuration: Misconfiguration in the planning area or master data settings can lead to unexpected large values being processed.
  Data Corruption: In some cases, corrupted data in the master data or transaction data can lead to erroneous calculations.
  
  Solutions:
  
  Check Input Values: Review the input values being used in the propagation calculation. Ensure that they are within reasonable limits and do not exceed the maximum values for the data types used.
  Adjust Data Types: If possible, consider adjusting the data types used in the calculations to accommodate larger values. This may involve changes in the configuration or data model.
  Review Configuration: Check the configuration of the planning area, including key figures and their settings. Ensure that they are set up correctly and that there are no misconfigurations leading to large values.
  Data Cleansing: Perform data cleansing to identify and correct any corrupted or erroneous data that may be causing the issue.
  Use Aggregation: If applicable, consider aggregating data to reduce the size of the numbers being processed. This can help avoid overflow issues.
  SAP Notes and Support: Check for any relevant SAP Notes that may address this specific error. SAP frequently releases updates and patches that may resolve known issues.
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for APO and the specific modules you are using to understand the limits and configurations better.
  SAP Community: Engage with the SAP Community forums to see if other users have encountered similar issues and what solutions they have found.
  Testing: If changes are made, ensure to test the propagation calculations in a development or quality assurance environment before applying them to production.
  
  If the issue persists after trying the above solutions, it may be necessary to involve SAP support for further investigation and assistance.
