Hello!
I have 2 sets of data in SAS Studio. The 1st data set has basic customer information (customer ID, city, state, etc...) and the 2nd data set has a listing of transaction by each customer. I need to append the customer data to the transaction data using the customer ID. I've tried using the merge function, but it then narrows down the transaction information down to 1 observation.
data transactions;
set CD8940.transaction_data;
run;
data customer_info;
set CD8940.customer_info;
run;
data merged;
merge transactions customer_info;
run;
Any help is greatly appreciated!
You did not provide any thing to tell the Merge to use the ID value. Which would be a BY ID statement if both sets are sorted by Id.
However Merge may run into issues with many-to-one (multiple transactions for one customer) and the order you place the data sets on a merge statement.
Proc SQL has many tools for combining data in interesting ways. One way:
proc sql; create table joined as select a.*, b.city, b.state from cd8940.transactiondata as a left join cd8940.customer_info as b on a.id = b.id ; quit;

Worked like a charm!
Thank you!
