Question

Why I can't use same connection in loop. Could you help me, please? I would explain step of all.

Step is as following:

1. "Get By Brand" block(Execute SQL Task): I query Brand data, output is object. For example the output is "AAA", "BBB" - The loop next step will run for two time.
2. "Foreach Loop by All Brand" block: First round of loop is passed. Second round of loop is not. Even though "Gen Header file" block(Data Flow Task) isn't change from first round - Connection and all is same from first round.

Second round of loop is error:

Answer 1

Since I use same connection in loop for many times. Therefore, I set property of connection name "RetainSameConnection" to True (Default is False). The problem is solved.
