I have multiple Stored Procedure Transaction Groups pointing to the same SPROC. Depending on the group, I pass the SPROC a number of values from devices as well as one or two fixed values (not originating from a device). How can I define a Group Item with a constant value? I’m trying to use Expression Items but I don’t believe I’m defining them correctly … after defining a value within General Properties \> Value and closing and opening Designer, the values aren’t persisting. Since I use the same SPROC in multiple places, I can’t define default values for my input parameters … Can someone help me with this? Do I need to define this within an expression (maybe using a SQL Query and the SELECT statement … ex. SELECT 1) or is there a simpler way? I feel like there’s a simple method to accomplishing this that I’m overlooking … Thanks in advance … ---

Let me clarify a bit … I know I can select SQL Query and enter SELECT 9 to have a constant value of 9 … I can also select Expression and enter 9 … Is there a way to setting a constant value without using an expression? ---

Yes, you should be able to just create an expression item and set the value, leaving the “expression mode” as none. Are you using the latest 7.0.3 version? I know we had a problem with the values of static tags/items, but I thought it was fixed before that version. In your case, you’re setting the value of the item and saving the group, but when it executes it shows 0? Regards, ---

> [@Colby.Clegg](#): > > Yes, you should be able to just create an expression item and set the value, leaving the "expression mode" as none. Ah, ok ... I thought that was the case but I was experiencing mixed results in my test environment ... I have been working with 7.0.3.4519 ... Yesterday, If I created an item, set the value and enabled the group, the value showed up as expected. If I disabled the group, closed Designer, opened Designer and enabled the group, the value returned to 0. Today, I'm not experiencing the above ... I'm able to enable/disable the group and close/open Designer and still maintain the expected value. I've even restarted the machine altogether and the value is still maintained. Therefore, it was most likely operator error 😊 I am finding that if I set a value and perform an export of the group (as XML), the value isn't maintained when the group is imported ... I've been doing that extensively in my test environment so I believe that may have been the source of my confusion ... ---

Ah, ok. We’ll look into the export/import. Regards,
