SAP Error Message - Details

• Message type: E = Error

• Message class: WA - Messages from Workflow Event Manager

• Message number: 630

• Message text: Type linkage between & & and &: Not possible to change check funct.mod.&

What causes this issue?

The function module which allows the event container to be evaluated
before the receiver function module is called (
<DS:GLOS.3526B0B1AFAB52B9E10000009B38F974>check function module</>)
cannot be changed for the specified type linkage between object type
and event and the specified receiver type.

System Response

The action was terminated, the check function module is not changed.

How to fix this error?

Check whether the specified type linkage exists.

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 WA630 - Type linkage between & & and &: Not possible to change check funct.mod.& ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WA630 Type linkage between & & and &: Not possible to change check funct.mod.&
  
  1. Cause:
  This error occurs during the activation or modification of ABAP programs or function modules when there is an inconsistency or conflict in the type linkage between the function module and its check function module.
  
  Type linkage refers to the relationship between a function module and its associated check function module (used for authorization or consistency checks).
  The system detects that the type linkage between the function module and the check function module cannot be changed because it would violate the existing linkage rules or integrity constraints.
  This usually happens if you try to change the check function module assigned to a function module or if the check function module's interface or type definitions have been altered incompatibly.
  
  
  2. When does it occur?
  
  When you try to change the check function module assigned to a function module in transaction SE37 or SE80.
  When you modify the interface of a check function module that is linked to other function modules.
  During transport or activation of function modules with inconsistent or incompatible check function module assignments.
  
  
  3. Solution:
  
  
  Check the linkage:
  
  Verify the current check function module assigned to the function module. You can do this in transaction SE37 by displaying the function module and checking the "Check Function Module" field.
  
  
  Do not change the check function module arbitrarily:
  
  If you need to change the check function module, ensure that the new check function module has a compatible interface and type linkage.
  
  
  Adjust interfaces consistently:
  
  If the check function module interface has changed, ensure that all function modules linked to it are updated accordingly or re-linked properly.
  
  
  Use consistent transport requests:
  
  When transporting function modules and their check function modules, ensure that all related objects are transported together to avoid inconsistencies.
  
  
  If necessary, remove and reassign:
  
  In some cases, you may need to remove the check function module assignment from the function module, activate it, and then assign a new check function module.
  
  
  Consult SAP Notes:
  
  Check for any SAP Notes related to this error message for specific patches or corrections.
  
  
  
  4. Related Information:
  
  
  Function Module Check Function Module:
  
  In SAP, function modules can have an associated check function module that performs authorization or consistency checks before the main function module executes.
  
  
  Transaction SE37:
  
  Used to display, create, or change function modules and their check function modules.
  
  
  SAP Notes and Documentation:
  
  Search for the message class WA6 and message number 30 in SAP OSS Notes or the SAP Support Portal for any updates or known issues.
  
  
  Example:
  
  If you have a function module Z_MY_FUNCTION linked to a check function module Z_CHECK_FUNC, and you try to assign a different check function module with incompatible parameters, this error will occur.
  
  
  
  Summary:
  
  
  
  Aspect
  Description
  
  
  
  
  Cause
  Attempt to change or assign a check function module to a function module with incompatible type linkage.
  
  
  Effect
  System prevents the change to maintain consistency and integrity of function module linkage.
  
  
  Solution
  Verify and maintain compatible check function modules; adjust interfaces consistently; transport related objects together.
