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.
