W8142
- Expression & refers to container elements that do not incorporate export ?Certainly! Here's a detailed explanation for the SAP error message:
SAP Error Message:
W8142 Expression & refers to container elements that do not incorporate export
Cause:
This warning occurs in SAP ABAP when you use an expression (typically in a function module call, method call, or a form call) that references container elements (like parameters or variables) which are not defined as EXPORTING parameters in the called procedure.
In other words, the expression you are passing refers to variables or parameters that are not marked for export from the called routine, but you are trying to use them as if they are.
For example, if you call a function module or method and pass a parameter that is not declared as EXPORTING (or RETURNING), but you try to use it as such, this warning is triggered.
Explanation:
You have a function module or method with parameters defined as IMPORTING or CHANGING, but you try to use them as EXPORTING in the call.
Example:
CALL FUNCTION 'Z_MY_FUNCTION'
EXPORTING
param1 = lv_value
IMPORTING
param2 = lv_result.
If param1
is not declared as EXPORTING in the function module interface, but you try to pass it as EXPORTING, the warning W8142 may appear.
Aspect | Description |
---|---|
Cause | Passing parameters as EXPORTING that are not declared as EXPORTING in the called routine. |
Effect | Warning W8142 is raised; potential mismatch in parameter passing direction. |
Solution | Check and align parameter directions between caller and called routine; correct the call. |
Notes | Warning only; program may run but with unexpected results if ignored. |
