using this filter: ['tranid', 'is', orderNumber], I am not getting the internal ID of the order. The Tran ID exist in system. Is this a valid filter? I think it is.

tranid is the document number I believe, not the internalid.... you want to use

internalid

anyof

I want internal id

Cannot use this. Order number is alpha numeric

I think I was misunderstood, you want to use the document number to find the internal id of the transaction, right? Looks like the correct term is

["numbertext", "is", orderNumber]

Tried that. Works with hardcoded value. Not when a variable is passed

works for me

I know. I ran the search twice. The hardcoded value has return the result.
