SAP Error Message - Details

• Message type: E = Error

• Message class: FDT_CORE - Formula & Derivation Tool: Core

• Message number: 158

• Message text: Multiple use of object in context/result not allowed (&1 and &2)

What causes this issue?

The system has determined that object &v1& is being used more than once
in the signature of the current expression. This can be due to any of
the following error situations:
Object is used both in the context and in the result.
Object is used more than once either in the context, in the result, or
both.
A typical reason how this error situation can occur is when you have
assigned an elementary data object and at the same time a structure or a
table object to an expression's context or result, and the elementary
data object is referenced by the complex data object. In such a
situation, the system cannot decide which of the both occurrences of the
elementary data object should be accessed.

System Response

The object cannot be activated.

How to fix this error?

Make sure all objects used in the context as well as in the result are
unique.
Tip: An easy way to fulfill this condition is to create a copy of the
data object that has been used more than once and then replace the
duplicate by the copy.

• What is the cause and solution for SAP error message FDT_CORE158 - Multiple use of object in context/result not allowed (&1 and &2) ?

  The SAP error message FDT_CORE158 indicates that there is a problem with the use of objects in a context or result within the SAP system. Specifically, it suggests that the same object is being used multiple times in a way that is not permitted. This can occur in various scenarios, particularly when working with Field Data Tool (FDT) or similar functionalities in SAP.
  Cause:
  The error typically arises due to one of the following reasons:
  
  Duplicate Object Usage: The same object (e.g., a field, data element, or structure) is being referenced multiple times in a context or result definition where only a single instance is allowed.
  Incorrect Configuration: There may be a misconfiguration in the way the objects are defined or linked within the FDT or other related tools.

  Modify Context/Result Definitions:
  
  If you find that an object is being used multiple times, modify the context or result definitions to eliminate the duplicate references.
  You may need to create separate contexts or results for different usages of the same object.
  
  
  
  Check Configuration:
  
  Review the configuration settings in the FDT or related tools to ensure that they are set up correctly.
  Make sure that the definitions align with the expected usage patterns of the objects.
