Modeler error messages - more info needed!

Question

Dear Friends,
I got an error executing a planning sequence of function type  'generate combinations'.
The system messages on the top section of the modeler  are :
1. first message :
"Planning function Gen Combinations ( ended with errors"
2. subsequent messages are in green (no error) 
"Context information for the other messages"
3. Selection for characteristic xyz : Single value 123  (no error)
:  <  similar ok messages follows >
2nd Error message :
"Cannot generate combinations for MultiProvider 'AGGR_LEVEL'"
this is followed by
3rd Error message :
"Cannot generate combinations in step 'xx'"
When double clicked on these error messages in the modeler, nothing appears to show more error info.
Could you experts kindly let me know how can I find out what these errors mean , specifically:
1. For the 3rd error, how can I know what is the step 'xx' about that the system is referring to where it cannot generate combinations?
2. What does it mean cannot generate combinations for multiprovider? Could you tell me more about what this means in terms of where is the problem?
Thanks in a advance!!

Answer 1

Dear Gregor,
For a planning sequence using planning function of type 'generate combinations', in general does this process work in the following sequential step ? :
1. check the filter
2. generate the combination based on filtered values
or    is it the other way round?
I am trying to know where the error lies since it errored so early in the process , about 3 seconds upon executing the sequence via program RSPLS_PLSEQ_EXECUTE.
I set break point on the class mentioned to no avail as the generate combinations sequence ended with error very early in the process.
I also set breakpoint on the characteristic relationship class used as well as standard variable exit include program. Also to no avail as the program errored before these stages as none of the breakpoints appeared in debug mode before the error.
The error message is " cannot generate combinations in step '04' "
Kindly could you shed more light on this error in terms of what it is referring to?
Is the problem with master data , filter or characteristic relationship?
Based on my testing done with breakpoints, seems that its not filter or characteristic relationship error.
So, does this mean master data error?
How could master data be having error?
Most characteristic relationship used are attribute types. There are 2 using classes.
Thank you in advance.
regards
YHogan
