SSRS - Need Help Understanding Expression

Question

First off, sorry if this has been asked before, but I could not find it anywhere. Searching for "=1'" did not return any results.

I am working on an Epicor SSRS report out of the box and do not know what part of the following expression means:

=1'=Sum(Fields!OrderRelNum.Value, "OrderRel")

Can anyone tell me what the first part of the expression (=1') is doing? I need to make changes to the report, but don't want to mess anything up.

Thanks in advance for any help.

撇号使该行的其余部分成为注释，因此将其忽略。
