How To Fix SWF_BND_001092 - Conversion From '&1' to '&2' Can Cause Data-Dependent Errors

SAP Error Message - Details

• Message type: E = Error

• Message class: SWF_BND_001 - Messages for workflow binding class

• Message number: 092

• Message text: Conversion From '&1' to '&2' Can Cause Data-Dependent Errors

What causes this issue?

The assignment between the data type &V1& and &V2& requires a conversion
at runtime of the workflow. This conversion can - depending on the
values then involved - lead to errors.
Examples:
An assignment between values of type integer (type <AB>I</>) and whole
numbers (type <AB>N</>) leads to errors if the integer value is
negative.
An assignment between a character string (type <AB>string</> or <AB>C
</>) and a number (type <AB>I</>, <AB>N</>, <AB>P</>, <AB>F</> ) leads
to errors if the content of the character string cannot be interpreted
as a number.
Assignment of a generic typed object to a fixed type object can cause an
error if the fixed object instances are not compatible at runtime.
Example: Assignment of an untyped BOR object (displayed as [BO.]) to a
typed BOR object (for example, type SOFM, displayed as [BO.SOFM]).
Assignment of an object reference of a father type to a derived type
(for example, [BO.FORMABSENC] to [BO.ZFORMABSENC]), a 'DownCast' can
call errors at runtime, if the variable of the father type does not
already contain a reference of the derived types. Alternatively, when
using BOR objects, always model on the father type and use Delegation on
the derived type.

System Response

A warning notifies you of the possibility of a runtime error.

How to fix this error?

Only use this assignment if you can guarantee that the conversion at
runtime of the workflow will not lead to errors. To rule out errors,
only use data types that are completely compatible.
If necessary, set the indicator <LS>ignore error</> for the assignment
operator in the binding. As a result, you ensure that the workflow is
not set to the status <ZK>error</> if an error occurs here. However, it
is your responsibility to model the subsequent process in such a way
that it also works correctly without the value to be transferred here.

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 SWF_BND_001092 - Conversion From '&1' to '&2' Can Cause Data-Dependent Errors ?

  The SAP error message SWF_BND_001092 indicates that there is a potential issue with data type conversion in your workflow or business process. This error typically arises when there is an attempt to convert data from one type to another, and the conversion may lead to data-dependent errors. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Data Type Mismatch: The error occurs when there is an attempt to convert a value from one data type (e.g., string, integer, date) to another, and the conversion is not guaranteed to be safe. For example, converting a string that does not represent a valid number into an integer can lead to errors.
  Inconsistent Data: The data being processed may not conform to the expected format or type, leading to conversion issues.
  Workflow Configuration: The workflow or process may be incorrectly configured, leading to attempts to convert incompatible data types.
  
  Solution:
  
  Check Data Types: Review the data types of the variables involved in the conversion. Ensure that the source data type is compatible with the target data type.
  Data Validation: Implement validation checks before performing conversions. Ensure that the data being converted is in the expected format and can be safely converted.
  Error Handling: Add error handling in your workflow to manage cases where conversion might fail. This can include logging the error and providing fallback mechanisms.
  Review Workflow Logic: Examine the workflow logic to ensure that the data flow is correct and that the right data types are being used at each step.
  Testing: Conduct thorough testing with various data inputs to identify any edge cases that may lead to conversion errors.
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for more details on data types and conversion functions.
  SAP Community: Engage with the SAP Community forums to see if others have encountered similar issues and what solutions they have implemented.
  Debugging Tools: Utilize SAP debugging tools to trace the workflow execution and identify where the conversion is failing.
  
  By addressing the underlying data type issues and ensuring proper validation and error handling, you can resolve the SWF_BND_001092 error and prevent it from occurring in the future.
