hey folks, if I have something like this in a Suitelet when the method is a POST (I am trying to save a form and update a field value on an item in the item sublist of a PO):

var params = context.request.parameters,

line = params.line,

// line, above, logs as a number, like 5

po = params.po,

options = {type:'purchaseorder', id:po, isDynamic: true},

rec = record.load(options);

var selected = rec.selectLine({

sublistId: "item",

line: line

});

I am getting this error:

Error: SSS_INVALID_SUBLIST_OPERATION

{"type":"error.SuiteScriptError","name":"SSS_INVALID_SUBLIST_OPERATION","message":"You have attempted an invalid sublist or line item operation. You are either trying to access a field on a non-existent line or you are trying to add or remove lines from a static sublist."

So the line exists... are item sublists not ediatable?

selecting lines is for dynamic mode

so when I load the record with isDynamic: true, that isn't dynamic mode?

so that looks correct, you might want to try hardcoding line to 0

so the issue with that is that it isn't line 0 that I want to update. I need to set the lines dynamically (that's why I am setting its value based on the parameters)... or maybe I am misunderstanding what line means in this case, but I can get the lines I need to return. if I hard code in the line I need to edit, like 5, I get the same error

how many lines on the purchase order

there are 8. I need to change 3 of the 8 . . . one of the 8 is line 5. I was trying to get this to work with just one of the 3 first... I am setting all this in the Suitlet when the method is GET

0 index based

so line isn't l

the line refers to line id

ok, well, that makes sense... I had line meanings mixed up

the line used in the suitescript api refers to the line sequence number

ok, that's a bummer for what I am trying to do, because I won't know the sequence in this case

load the record and find the matching line

thanks for your help... is there a better way to edit PO item sublist field values when saved via form in a Suitelet?

you can check each row, or use Record.findSublistLineWithValue(options)

ok, thanks. I'll have to try some things. I am attempting to set a received by date field on certain items in the sublist, so the form has multiple date inputs
