How to turn off Unique/Required for elements with a command? 

Using Export/Import on records with two Unique, Mandatory fields.  If I import with field copied, get message cannot save as unique. If I import without field, I get cannot save without mandatory field.   

Subroutine flow is this:
1. Make sure there is only one record in Result Set.
2.  Export record A. (Order with line items on subform)
3.  Import export file from A and save as record B.
4.  Remove record A from record set.
5.  Modify some values on Record B including making new Unique values in those two elements.
6.  Loop thru subform lines to update new unique fields.

Note this an Order form with line items on subform.   The subform lines also have similar unique elements.

The import process is not saving the new record B, so I cannot proceed any further. I cannot go past Step 3, because of the error messages.

I thought as a solution I could disable Unique, do import, update new fields and then enable Unique again.  But cannot find such a command.  Does it exist?  Whree?  If not, any suggestions on how to solve this? 

Thanks Ray, that should do it.  And what is the attr value to reset it again?  Yes/True/1/??)
Attribute(ElementName, 38, ???)

Not at system now, but it looks like if I run @Attribute(ElementName) it will return the correct value, and that is what I will use.  Does that sound correct?

Ok, I was able to get the different values for Restriction and Unique (Attribute of READ_ONLY)

Restricted = "!" and ""

ReadOnly values are:
No = "0"
Unique = "0"
Yes, grayed out =  "1"
Yes, not grayed out = "2"

I would have thought that four different states would have four different values.  Is it intentional that NO and UNIQUE both have the same value?  If I reset that attribute to 0 how does that make the element unique, it only makes it not ReadOnly.

Thanks Ray, I found that out.  This is the code I was using:

	// Turn off Mandatory and Unique to allow new record to be saved. Reset at end of process.
	Attribute(OrderNumber,28,"0")			// Turn off Unique
	Attribute(OrderNumber,38,"")			// Turn off Mandatory
	Attribute(Record,28,"0")			// Turn off Unique
	Attribute(Record,38,"")				// Turn off Mandatory

	FormAttribute("OrderLines","Record",38,"")	// Turn off Mandatory on subform for line items.
	// ==================
 

Mandatory seemed to be working, but not Unique.  I tried using values of "" and "3", with no success.

You said I cannot change it with the ReadOnly attribute, is there another way to do this? 

If not, can we get this capability added to the current list of attribute variables in a future release?

Sounds good, will try that tonight.  Thanks.
