Setting Variable Values From Within A Data Flow

Hello There:
I am running a data flow within a ForEach loop wherein I am computing a value called QuotaGap. When it is 0 I do not want any further execution of the loop. I am using a Conditional Transform within this dataflow that writes a record to a table only when the QuotaGap is NOT 0. However, I am unable to terminate the execution of the loop as I am still within the dataflow.

Now, the computation of the gap requires a value from another variable called NetPurchases. I tried using an ExecuteSQL task in the control flow but could not figure out how to pass the value of the variable NetPurchases into the select statement to compute the gap. For example, the select statement would read:


select (QuotaUpperLimit - ?) As QuotaGap from <<tablename>>

I tried setting the parameter as an input as well as an output and it did not work.

Then I tried passing the entire SQL as a string within a variable. This does not work either because in order to compute the math QuotaUpperLimit - NetPurchases, both variables need to be integers but then you cannot concatenate integres together, which is what we need to do to create the SQL.

The other reason I am going through these hoops I guess is that I have not figured out a way to set the value of a variable within a data flow. I compute the value for QuotaGap within the dataflow in a ForEach loop but I have no way to pass this result to a variable called QuotaGap without using an ExecuteSQL task or another ForEach Loop.


I have spent hours on this simple issue and so have given up and looking to the good friends in this forum for help.

If what I have stated is not clear please let me know and I will try to clarify things a bit.

Thanks!
