Merge

while merging data i got following error, can anyone look at it and tell me how to deal with it.

This message is telling you that COMPANY is part of both data sets that you are merging.  However, it has a different length in the two data sets.  You would need to examine the length (probably running  PROC CONTENTS on both data sets), select the longer length, and use that to define COMPANY.  You would do that by adding this sort of statement (using the longer length rather than 20):

length company $ 20;

It has to go BEFORE the MERGE statement.

Or if the first dataset in the merge statement (E1 in your case) has company with the longer length, it will prevail.

In general the first encounter with a variable establishes its attributes (length, format, label), while the last encounter establishes the value.
