SAP Error Message - Details

• Message type: E = Error

• Message class: SWF_BND_001 - Messages for workflow binding class

• Message number: 094

• Message text: Structures of type '&1' and '&2' are not compatible

What causes this issue?

A structure of type &V1& cannot be assigned as a whole to a structure
of type &V2& due to the technical attributes of its sub-fields (number,
length, data type).

System Response

This assignment leads to an error in the binding check.

How to fix this error?

For each of the sub-fields of the source structure to be transferred,
create a separate binding row with an instruction of the following
type.
Structure.Sub-field -> Structure.Sub-field

• What is the cause and solution for SAP error message SWF_BND_001094 - Structures of type '&1' and '&2' are not compatible ?

  The SAP error message SWF_BND_001094 indicates that there is a compatibility issue between two structures in a workflow binding. This typically occurs when you are trying to bind data from one structure to another, but the structures do not match in terms of their fields or data types.
  Cause:
  
  Mismatched Structures: The two structures being compared or bound have different field names, types, or lengths. This can happen if the structures were modified or if there is a version mismatch.
  Incorrect Mapping: The mapping of fields between the two structures may not be correctly defined, leading to incompatibility.
  Changes in Data Model: If there have been recent changes to the data model or the structures involved, it may lead to this error if the workflow is not updated accordingly.
  
  Solution:
  
  Check Structure Definitions: Review the definitions of both structures involved in the binding. Ensure that they have compatible fields (same names, types, and lengths).
  Update Workflow: If there have been changes to the structures, update the workflow to reflect these changes. This may involve re-mapping fields or adjusting the workflow logic.
  Use Compatible Structures: If you are using custom structures, ensure that they are designed to be compatible with the standard structures you are trying to bind to.
  Debugging: Use transaction SWI1 (Work Item Selection) or SWI2_FREQ (Work Item Analysis) to analyze the workflow and identify where the binding is failing. This can help pinpoint the exact location of the issue.
  Consult Documentation: Refer to SAP documentation or notes related to the specific structures you are working with to ensure you are following best practices.
