• What is the cause and solution for SAP error message FDT_EXPRESSIONS220 - Lines &1 have similar value/test parameter ?

  The SAP error message FDT_EXPRESSIONS220 indicates that there are multiple lines in a decision table or expression that have similar or identical value/test parameters. This can lead to ambiguity in the decision-making process, as the system may not know which line to prioritize when evaluating the conditions.
  Cause:
  The error typically arises in the context of using decision tables or expressions in SAP applications, particularly in the context of Business Rules Framework (BRF+). The specific causes include:
  
  Duplicate entries in the decision table where multiple lines have the same or similar conditions.

  Review the Decision Table/Expression:

  Test Changes:
  
  After making the necessary adjustments, test the decision table or expression to ensure that it functions as expected without generating the error.
