• What is the cause and solution for SAP error message /PM0/ABJ_MSG171 - Date input not ascending ?

  The SAP error message /PM0/ABJ_MSG171 with the description "Date input not ascending" typically occurs in the context of project management or maintenance planning when the system expects a series of dates to be entered in a strictly ascending order, but the provided dates do not meet this requirement.
  Cause:
  The error is triggered when:
  
  You are trying to enter multiple dates (e.g., start dates, end dates, or planned dates) in a sequence, and at least one of the dates is not greater than the previous date.
  For example, if you enter a start date of January 5, 2023, and then try to enter a subsequent date of January 3, 2023, the system will raise this error because the dates are not in ascending order.
  
  Solution:
  To resolve this error, you should:
  
  
  Review the Dates: Check all the date fields you have entered to ensure they are in ascending order.
  
  
  Correct the Order: Adjust the dates so that each subsequent date is greater than the previous one. For example, if you have:
  
  Date 1: January 1, 2023
  Date 2: January 3, 2023
  Date 3: January 2, 2023 (this is incorrect)
  
  You should change Date 3 to a date that is after January 3, 2023 (e.g., January 4, 2023).
  
  
  Re-enter the Data: After making the necessary adjustments, re-enter the data and save the changes.
