what is the difference between EX AND EC IN SDTM?

When posting a question, please provide a body of the post.  Also avoid using all upcase as it is rude and sounds like shouting.  With regards to your question, CDISC modelling has nothing to do with SAS programming, they are different things.  To get information on CDISC models and their use consult the SDTM or ADaM implementation guides which can be downloaded via the cdisc.org website after you have logged in there.  Here is a paper on the subject:

Hello!
I'm trying to do a EG domain so that I've a raw data set which should be converted to the standard SDTM EG domain like EG(example has given in that one) in SDTMIG guidance.
Could you please help me out for how to do that one..

EX: By SDTM definition it says,
1. It captures all the subjects exposure data that is specified in the protocol.
2. It captures the data in units that are specified in the protocol. The protocol will already specify what units are to be used.

EC:
1. As said, subjects might miss their visit or will have unscheduled visits. Then in that case, subject will have different date other than protocol specified date. That exposure data will be collected in EC.
2. Some time local labs will use their own measurement system. If the study is in different countries, then their local lab uses different system units instead of protocol specified units. Those are captured exactly the way they were collected. For example, if the protocol specified units were collected cm and the local lab collected in inches. Then inches are captured in EC.

These are the 2 main difference you may find between EX and EC.
