• What is the cause and solution for SAP error message UCM1005 - The sum of percentage rates does not equal 100 % ?

  The SAP error message UCM1005, "The sum of percentage rates does not equal 100 %," typically occurs in the context of configuring or processing certain financial or controlling documents, such as cost allocations, profit center accounting, or internal orders. This error indicates that the total of the percentage rates you have entered does not add up to 100%, which is a requirement for the system to process the data correctly.
  Cause:
  
  Incorrect Percentage Entries: The most common cause is that the user has entered percentage values that do not sum to 100%. For example, if you have three entries of 30%, 40%, and 20%, the total is 90%, which will trigger this error.
  Missing Entries: If you have not entered all the required percentage rates for a particular allocation or distribution, the system will not be able to calculate the total correctly.
  Rounding Issues: Sometimes, rounding can lead to discrepancies where the total appears to be close to 100% but does not exactly equal it due to decimal places.
  
  Solution:
  
  Check Entries: Review all percentage entries in the relevant transaction or configuration screen. Ensure that they add up to exactly 100%. 
  Adjust Percentages: If you find that the percentages do not sum to 100%, adjust them accordingly. You may need to redistribute the percentages among the various entries.
  Add Missing Entries: If you have omitted any entries, add them to ensure that the total reaches 100%.
  Rounding Considerations: If rounding is an issue, consider adjusting the percentages to account for rounding differences, ensuring that the total is still 100%.
