Why we need to set "Create Transaction Id set to Yes in table for table type "Regular table" in SSRS report

Dear All,

When we are creating SSRS report with "Regular Table" then in TempTable > properties

we set

1. Table Type : Regular and
Create Transaction Id = YES.

2.We need to create 2 methods for Temp Table
get() and

set()

3. Process Report() :

TempTable.setConnection(this.ParmUserConnection);

Can you please let me know why we need to set "Create Transaction Id set to Yes.

What it's does ?

Please give me more shed on this.

Thanks!

Arpan
