How To Fix FDT_SERVICE078 - Collision for function &1 could not be resolved automatically

SAP Error Message - Details

• Message type: E = Error

• Message class: FDT_SERVICE - Formula & Derivation Tool: Services

• Message number: 078

• Message text: Collision for function &1 could not be resolved automatically

What causes this issue?

A collision occurred during the deployment of an BRFplus function. This
means that a customer version of that rule exists actively in the
system. Furthermore this customer version was created on the basis of an
older version than the one that is actually about to be deployed. Since
the customer version may not be overwritten with the new version, the
new version cannot be deployed. This is called a collision.
The BRFplus service provider tried to resolve this collision by checking
the compatibility of the two versions. Unfortunately it was not possible
to resolve the collision automatically. This means that an incompatible
change for that rule has been shipped.

System Response

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

How to fix this error?

To enable a deployment of the incompatibly changed rule, a deployment
exit needs to be provided. Contact the owner of the rule with this
request.

  Function Name Collision: The error usually arises when there are multiple functions defined with the same name or signature in the system, and the framework is unable to determine which one to use.
  Configuration Issues: There may be issues in the configuration of the FDT or FDI settings, leading to ambiguity in function resolution.
  Custom Development: If there are custom functions or enhancements that have not been properly managed, they may conflict with standard functions.

  Solution:
  
  Check Function Definitions: Review the function definitions in the FDT framework to identify any duplicates. Ensure that each function has a unique name and signature.
  Adjust Configuration: If the issue is related to configuration, adjust the settings in the FDT or FDI configuration to resolve the ambiguity.

  Custom Code Review: If custom code is involved, review it to ensure that it does not conflict with standard SAP functions. Refactor or rename custom functions if necessary.
  Transport Management: Ensure that all transports are correctly managed and that the target system has the same function definitions as the source system.
  SAP Notes: Check for any relevant SAP Notes or updates that may address this issue. SAP frequently releases patches and notes that can resolve known issues.
