Error While Creating Material Classification Characteristic DataSource -

Question

Hi  All,
    I am creating the Material Classification DataSource 1CL_OMAT001 with CTBW in R/3 with the following info:
Basis DataSource = 0MATERIAL_ATTR; Client = 200; Class Type = 001;
Obj table = MARA; DataSource Type = ATTR,  DataSource = 1CL_OMAT001
I have added all the characteristics with 'New Entries' button and the following are the details after saving it:
   DataSource = 1CL_OMAT001
   Characteristic Name =  ABCDXYZ
   Item No =   '    ' (blank)
   Maintain Status =  N
   Characteristic = 1CL_AABC001
   Typ  =  CHA
   While adding the MATERIAL_GROUP as characteristic it got an error because of Reference Characteristic since it is reference to Table MARA. Finally, I didn't add it.
   When I click the 'Generate' button to generate the DataSource then it is giving the error of <b>'BW Metada is incomplete'</b>  (CLBW008).
   What is wrong with it and how could I fix this problem, please ?
   Thanks in advance.

I am not too sure but this might be the cause of error. Data doesn't need to be in client 100, but the characteristic needs to be defined in the class if I remember it correctly.
To do a quick check, open report program RCLBW_STRUCTURE_GEN in SE38, there is a call to FM RSA1_SINGLE_OLTPSOURCE_GET (around line 169) put a breakpoint there in the editor (display).
Now run your CTBW generation, it should stop at the breakpoint. You should check the value of field GT_CLBW_SOURCES-IOBJNM in the debugger - it would likely be the characteristic name.
Now, go to SE37, do a single test of FM RSA1_SINGLE_OLTPSOURCE_GET, and specify this same value for field I_OLTPSOURCE and execute. You will likely get a sy-subrc of non-zero.
Repeat this in client 200, check sy-subrc.
If you are getting sy-subrc 0 in 200 and non-zero in 100; you will either need to create the classification in 100, or generate it in 200.
If this doesn't work, let us know.
