Nav attribute in where-statement

Question

Hi Experts,
I have a routine in which I want to select 0MAT_SALES where my navigation attribute ZACCASGRP equals some values. I have written the code below but I get a syntax error when trying to compile it. I do not get any suggestions and I have not been able to figure out the problem.
data: BEGIN OF Z_FUNDGROUP occurs 0,
    /BI0/OIMAT_SALES TYPE /BIC/AZBILCOPA00-MAT_SALES,
END OF Z_FUNDGROUP.
SELECT * FROM /BIC/AZBILCOPA00
    Into corresponding fields of table Z_FUNDGROUP
        where MAT_SALES-ZACCASGRP IN ('a', 'b', 'c').
My problem is the where-statement and I have also tried with the following combinations but non of them works:
/BI0/OIMAT_SALES-ZACCASGRP
/BI0/OIMAT_SALES-0MAT_SALES__ZACCASGRP
MAT_SALES-0MAT_SALES__ZACCASGRP
if I change it to only say: where MAT_SALES IN ('a', 'b', 'c'). I do not get the error (but this is of course useless since I am not restricting on my navigation attrivute).
Can somebody please help me with this.
Thank you in advance,
Mikael

Hi,
You are probably right regarding the Select-statement above. I therefore reasoned that I should be able to re-structure my problem and use the following select-statements instead:
SELECT MAT_SALES
    FROM /BI0/PMAT_SALES
    INTO TABLE Z_FUNDGROUP
    WHERE
        MAT_SALES IN (
            SELECT DISTINCT MAT_SALES
                FROM /BIC/AZBILCOPA00
        AND /BIC/ZACCASGRP IN ('a', 'b', 'c').
but when I do this I still get errors. If I skip the "AND /BIC/ZACCASGRP IN ('a', 'b', 'c')" part it gives me valid results, but I have to be able to use this attribute. When I look at the master data table /BI0/PMAT_SALES in SE16 it shows me that there is a field named /BIC/ZACCASGRP and then I do not understand why I cannot use the above select.
Best regards,
