how long eVar expire with purchaseID will persist?

[dinesh_kumar_r]

If user doesn't complete the goal after starting it(which is captured in eVar1) with in the same visit or in the next 3/4 visits, then also eVar value will persist or it will expire? if expire then when it will?

I assume you mean that your eVar's Expiration setting has been set to be some success event, e.g. "Purchase". If the user never does something to cause that success event to fire, e.g. he never makes a purchase, then the eVar will continue to persist forever and ever until he finally causes the success event to fire, i.e. makes a purchase.

Hi @yuhuisg - 
If there is an eVar with expiration set to Purchase. If I come back and visit again ... would my eVar update with the new value or would it only show the original value? 

The eVar is set to Most Recent Last + set to purchase... no merchandising or binding events

I have a client that uses an eVar for marketing channels. Marketing Channel Expiration set to 30 days... eVar set to expire on Purchase.

Let's say your user, Tom, does this:

Monday:

12:00pm: Views homepage.

12:05pm: Clicks Promotion X. --> track "Promotion X" to eVar23.

12:10pm: Leaves the website.

...

4:00pm: Views homepage.

4:10pm: Clicks Promotion Y. --> track "Promotion Y" to eVar23.

4:20pm: Leaves the website.

Tuesday:

10:00am: Views homepage.

10:20am: Completes the purchase. --> track Success Event "purchase".

10:30am: Views homepage.

10:35am: Clicks Promotion Z. --> track "Promotion Z" to eVar23.

10:50am: Completes the purchase. --> track Success Event "purchase".

Result in AA:

eVar23 | Visits | Purchases

--------------------------

Total | 3 | 2

Promotion Y | 2 | 1

Promotion Z | 1 | 1

Promotion X | 1 | 0

Because your eVar's Expiration is set to "Most Recent", so the last-set values ("Promotion Y", "Promotion Z") gets credit for the purchase.
