Values are not populated properly - if then else conditon

Hi,

I 've a requirement like...

If meinh = ZTU then lfimg/umrez else display the values of lfimg

I 've used if then else condition afterthat i mapped to target field lfimg. But, when i check the queue the result displays correctly, but when i execute the mapping from Test tab it displays all the values for LFIMG

My question here is ...Why the output is not display properly after i use if then else condition

Help me how can i get proper values to display at target

Kind regards,
