Error while generating Work Order

Question

I have a problem while generating Work orders in SNC.
I set the configuration as belows.
<General setting for Work Order generation>
1.Granularity -> Work Order per Purchase Order Item
2.Create WOs with Report -> Check
3.Publish Work Order Upon Creation and PO change -> check
4.Send Work Order Information -> Upon Agreement and when a Phase Is Completed
5.Send Production Progress Notification -> When a Phase Is Completed
<Phase Structure>
1.Comp. from SC Order -> Use SC Comp. as Input, Product and Co-Products as Output
<Master Data Assignment>
1.MD Used for WO -> Phase Structure
2.Active -> Check
When I use the program /SCA/WO_CREATE for generate Work Orders, Run time error occurs with below messages.
Runtime Errors         OBJECTS_OBJREF_NOT_ASSIGNED
Except.                CX_SY_REF_IS_INITIAL
<Error analysis>
The exception, which is assigned to class 'CX_SY_REF_IS_INITIAL', was not caught in
procedure "GET_PIO_LCTYPE" "(METHOD)", nor was it propagated by a RAISING clause.
Since the caller of the procedure could not have anticipated that the exception would occur, the current program is terminated.
The reason for the exception is:
You attempted to use a 'NULL' object reference (points to 'nothing')
access a component (variable: "LS_NODEREF-R_NODE").
An object reference must point to an object (an instance of a class)
before it can be used to access components.
Either the reference was never set or it was set to 'NULL' using the
CLEAR statement.
<Missing RAISING Clause in Interface>
Program                                 /SCA/CL_WO_PHASE==============CP
Include                                 /SCA/CL_WO_PHASE==============CM00V

Please let me know what I have to do for this error.
Thanks and Regards

Answer 1

Hi JT
Clearly the problem is with the method GET_PIO_LCTYPE of interface /SCA/CL_WO_PHASE
Check whether note 1363834 should be implemented
It could be because of some corrupted WO entries in database
or some customizing entry it is expecting
suggest you to debug the method and try to check what it is expecting
