NODE_KEY_EXISTS" raised in /SAPAPO/CONSCHK

Question

Hello,
We are running transaction /SAPAPO/CONSCHK in our SCM system v. 5.0.  When I click the "Object Selection" button using any selection criteria, I get the following short dump:
Short text
    Exception condition "NODE_KEY_EXISTS" raised.
Error analysis
    A RAISE statement in the program "CL_SIMPLE_TREE_MODEL==========CP" raised the
     exception condition "NODE_KEY_EXISTS".
    Since the exception was not intercepted by a superior
    program, processing was terminated.
Information on where terminated
    Termination occurred in the ABAP program "CL_SIMPLE_TREE_MODEL==========CP" -
     in "ADD_NODE".
    The main program was "/SAPAPO/SAPLMVM_CONS ".
    In the source code you have the termination point in line 38
    of the (Include) program "CL_SIMPLE_TREE_MODEL==========CM001".
The exception is raised in method add_node_int of Class CL_TREE_MODEL.
Thank you for any help and suggestions.
Kind regards,
Chris

Answer 1

The root cause seems to be inconsistency in the WorkArea selected.
Quick of checking it is goto /SAPAPO/CONSCHK transaction enter the Planning version, Work Area and Consistency Profile and then click on Object Selection button. It should display the location-product combinations added in the WorkArea if it does not display that (most likely will generate a short dump) you need check the Work Area going into /SAPAPO/SCC02.
Hope this helps.
