I would like to collapse the below records (screenshot) that have the same entity_id into one record and keep all the column values, where one is populated.
Is there a fairly straight forward way of doing this?
Glad to read that it worked for you.
Maybe you have used (or heard of) PROC MEANS? It's almost the same, but writes to the output window by default.
The option MAX= of the OUTPUT statement says that
By default, the output dataset contains variables _TYPE_ and _FREQ_ containing additional information about the summary: In your example, _TYPE_=1 for all observations, hence not very interesting, _FREQ_ = number of observations summarized, i.e. 3 for entity_id=165771, 5 for entity_id=230674, ... Assuming that you don't need these variables, I dropped them. More precisely: I dropped all variables whose names start with an underscore.
* Here, the VAR statement contains the list of all variables in dataset HAVE whose names start with "SubPh" (assuming that these are exactly your intended analysis variables).
