I don't even use the SAS Flow Manager...
But I typed "SAS flow manager dependencies" into Google, and got "About 626,000 results".
Perhaps you should read the first few hits?
Please post your question as a self-contained data step in the form of "have" (source) and "want" (desired results).
I won't contribute to your post if I can't cut-and-paste your syntactically correct code into SAS.
