           AND werks IN p_werks
           AND charg EQ matnr_101-charg
           AND bwart = '101'.

Answer 1

Hi,
1 .Dont use * from any table.
2. Create  a internal table  that u want to retrieve the data from that table. (Structure).
Eg:
types : begin of str_ekko,
           ebeln type ekko-ebeln,
           bsart type ekko-bsart,
           aedat type ekko-aedat,
           endof str_ekko.
data : itab type table of str_ekko,
        wa_itab type str_ekko.
In the above u want to take care that while creating the structure u want to look the sequence of fields in the table. in the same sequence u want to create the structure.
3 . The Select-options fields also wants be in the same field sequence of the table.
eg : select ebeln bsart aedat from ekko into table itab where ebeln in so_ebeln and                                                                               
bsart in so_bsart and
                                                                                aedat in so_aedat.
4.  If the above things are not working just look the indexes of that table. Just create a secondary index with ur requirement.
