How To Fix W8088 - Source & corresponds to object type & and not &

SAP Error Message - Details

• Message type: E = Error

• Message class: W8 - Workflow: Expressions, data flow

• Message number: 088

• Message text: Source & corresponds to object type & and not &

What causes this issue?

The two partners of the value assignment in a binding definition must
be defined by <zh>identical data types</> or at least <zh>compatible
data types</>.
Data types expressed with an <zh>object type</> count as compatible if:
no object type is explicitly specified for the target element,
(assignment: specified object reference ==> unspecified object
reference)
the source element references a subtype of the object type which is
referenced by the target element
(assignment: object reference subtype ==> object reference parent type)
In the binding definition to which this warning relates, you are
assigning two object types to each other which are not compatible
according to these guidelines, but do however possess compatible key
structures: Object type &v2& is not a subtype of object type &v3& but
both these object types have an identical key structure according to
domain.
No runtime inconsistencies occur via a binding of this kind, but
semantic accuracy cannot be ensured because of the object type
hierarchy.

• What is the cause and solution for SAP error message W8088 - Source & corresponds to object type & and not & ?

  Certainly! Here's a detailed explanation for the SAP error message W8088:
  
  SAP Message W8088
  Message Text:
  
  Source & corresponds to object type & and not &
  
  Cause
  This warning message occurs when there is a mismatch between the source object type and the expected object type in a particular SAP process or transaction. Essentially, the system is indicating that the source object you are trying to use or reference corresponds to a different object type than what is expected or allowed in the current context.
  For example, you might be trying to assign or link an object of type "Material" (MARA) where the system expects an object of type "Customer" (KNA1), or vice versa.
  
  Typical Scenarios
  
  When working with Business Objects in SAP (e.g., in workflows, ALE, IDocs, or BAPIs), the system expects a certain object type but receives a different one.
  During data transfer or mapping between systems or modules, the object type does not match the expected type.
  In custom developments or enhancements, where object types are checked or validated.
  When using transaction codes or functions that require a specific object type as input.
  
  
  Solution
  
  
  Check the Object Types:
  
  Identify the source object and its type.
  Verify the expected object type in the context where the error occurs.
  
  
  
  Correct the Object Reference:
  
  Ensure that the object you are referencing or passing matches the expected object type.
  If you are using a custom program or enhancement, adjust the logic to pass the correct object type.
  
  
  
  Review Configuration:
  
  If this occurs in a standard SAP process (e.g., workflow, ALE), check the configuration to ensure that the object types are correctly defined and mapped.
  
  
  
  Debugging:
  
  Use debugging tools (e.g., ABAP debugger) to trace where the mismatch happens.
  Check the values of the variables representing the source and expected object types.
  
  
  
  Consult Documentation:
  
  Look up the specific transaction or function module documentation to understand the expected object types.
  
  
  
  
  Related Information
  
  
  Object Types in SAP:
  
  SAP uses object types to categorize business objects (e.g., materials, customers, vendors, documents). Each object type has a unique identifier.
  
  
  Message Class:
  
  This message usually belongs to a specific message class related to the module or function you are working with (e.g., workflow, ALE).
  
  
  Example:
  
  If the message reads:
  
  Source 12345 corresponds to object type MARA and not KNA1
  
  It means object 12345 is a material, but the system expected a customer.
  
  
  Transaction Codes:
  
  This message can appear in various transactions depending on the context, such as SWI1 (Workflow), BD87 (IDoc processing), or custom transactions.
  
  
  
  If you provide the exact context or transaction where you encounter this message, I can help you with more specific guidance.
