Logic needed for dynamic report

Question

Hi Experts,
I have made a dynamic report where my logic is if the value of the columns is 0 than it should be blank and if the columns of the stores have some value for eg: 01 than it should populate the same store.
The logic goes like :
for matnr     01store 02 store
                                         01       100.00          0.00
                                         02          00              00
                                         03       50.00           13.00
than the output should be
matnr     01store 02 store
                                         01           01store       
                                         02        
                                         03           01store    02 store
I have made the logic but all the lines are getting appended
it_field_dynamic1-fieldname = 'MATNR'.
    it_field_dynamic1-desc      = 'ARTICLE'.
    it_field_dynamic1-reffield = 'MATNR'.
    it_field_dynamic1-reftab   = 'MBEW'.
    it_field_dynamic1-seq =  1.

than i have called the alv grid display
Please let me know.

Hi Oliver,
My current output is:
for                                  
matnr     01store 02 store
                                                  01         100.00         0.00
                                                   02          00              00
                                                   03       50.00           13.00
                                        matnr    01store   02 store
                                         01       01store         
                                         02       01store            
                                         03       01store
but for matnr 02,  01 store has 0 value hence it should come blank but its appending from the first line and populating 01store for material 2.
Thanks & Regards,
Nikhil.
