How To Fix FDT_EXPRESSIONS141 - Line &1 overlaps with line &2 (lines not independent)

SAP Error Message - Details

• Message type: E = Error

• Message class: FDT_EXPRESSIONS - Formula & Derivation Tool: Expressions

• Message number: 141

• Message text: Line &1 overlaps with line &2 (lines not independent)

What causes this issue?

In the current decision table, the conditions you have entered in lines
&V1& and &V2& are overlapping.
However, for the system to work properly, it is mandatory to either have
a clear semantic separation between each condition or to organize the
conditions in such a way that they are focused on a scale of increasing
generality. Partially overlapping conditions are not allowed in order to
prevent the system from having to solve ambiguous situations.

System Response

The decision table cannot be activated.

How to fix this error?

Reorganize the conditions in the decision table such that they do not
contain any overlapping ranges.

Procedure for System Administrators

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message FDT_EXPRESSIONS141 - Line &1 overlaps with line &2 (lines not independent) ?

  The SAP error message FDT_EXPRESSIONS141 indicates that there is an issue with overlapping lines in a data transformation or expression within the SAP system, specifically in the context of the SAP Financial Data Transformation (FDT) framework. This error typically arises when two or more lines in a transformation or expression are not independent of each other, meaning that they are trying to access or manipulate the same data in a conflicting manner.
  Cause:
  
  Overlapping Ranges: The error occurs when the ranges defined in the transformation overlap. For example, if you have two lines that are supposed to process different sets of data but they end up covering the same data range, this will trigger the error.
  Incorrect Logic: The logic defined in the transformation may not be correctly set up, leading to dependencies between lines that should be independent.
  Misconfiguration: There may be a misconfiguration in the transformation settings or parameters that causes the lines to overlap.
  
  Solution:
  
  Review the Transformation Logic: Check the logic defined in the transformation. Ensure that each line is processing distinct and non-overlapping data ranges.
  Adjust Ranges: Modify the ranges or conditions defined in the lines to ensure they do not overlap. This may involve changing the criteria or the data being processed.
  Check Dependencies: Ensure that the lines are independent. If one line depends on the output of another, consider restructuring the transformation to eliminate this dependency.
  Testing: After making adjustments, test the transformation to ensure that the error no longer occurs and that the desired results are achieved.
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for the FDT framework for detailed guidelines on setting up transformations and expressions.
  SAP Community: Engage with the SAP Community forums to see if others have encountered similar issues and how they resolved them.
  Debugging Tools: Utilize SAP debugging tools to trace the execution of the transformation and identify where the overlap occurs.
  
  By addressing the overlapping lines and ensuring that each line operates independently, you should be able to resolve the FDT_EXPRESSIONS141 error.
