How to find the list of material variant based on the characteristics value

Question

Hi
We are creating materials variants for FERT Material Type in material master in MRP-3 view .There we configure the variant by attaching characteristics value 
Now we want to have a report , which can give the list of material variants , if char value is given in selection
Can somebody guide me if there is standard report for this OR what is the linkage in Table , so that we can develop a report

Answer 1

I couldn't find a standard report to get the material variants based on characteristic values (the nearest I could find was CT12) but I wrote a report some time back here's the table join logic for the main select statement.
select a~matnr
        e~atwrt
        h~atwtb
into table i_tab
      from MARC as a
      inner join IBIN as b
      on b~instance eq a~cuobj
      inner join IBIB as c
      on c~ibase eq b~ibase
      inner join IBINVALUES as d
      on d~in_recno eq b~in_recno
      inner join IBSYMBOL as e
      on e~symbol_id eq d~symbol_id
      inner join CABN as f
      on f~atinn eq e~atinn
      inner join CAWN as g
      on g~atinn eq e~atinn
      and g~atwrt eq e~atwrt
      inner join CAWNT as h
      on h~atinn eq g~atinn
      and h~atzhl eq g~atzhl
     where     a~matnr in s_matnr
            and e~atinn in s_atinn
            and e~atwrt in s_atwrt
           and b~valto eq '99991231235959'. "This is important condition
I included bare minimum fields to suite your requirement needs you can add whatever other field you want . Though I tested the table join, I suggest you to test it again before writing your own ABAP program using SE16N.
