Hi Naveen,

Thanks for you reply.

I need to merge two data sets. The merge is between 2 tables and I need to take the values ​​of Table 2 in case in Table 1 have in those places a specific value and in the rest of the cases take the values of Table 1.

Do you understand?

Thank you very much

Maria

Well, if certain conditions are in place ... like both tables contain at most one observation per ID ... you could try it like this:

data table1_revised;

  set table1;

  if name='Specific Value' then name=' ';

run;

data want;

  update table2 (in=in2 keep=id name) table1_revised (in=in1);

  by id;

  if in1;

run;
