Hi all,

I am developing a form which is similar to the purchase order and where as I have a header table and line table.

In line table I have added the a field linenum and I wanted to know how the linenumber gets assigned every time we create a new record in the purchase line so that I can implement that thing in my form too,

Please through some lights on that.

SO far I have added a field and added the same EDT which is given over there in the purchase line but not sure how the purchase line number gets assigned every time we create a new line.

Thanks you

Hi Rohit,

You can take a look at Classes\TradeLineNumberManager\doUpdateLineNumber method as well. This method uses the lastLineNumber method Vinit mentioned and adds the increment from System parameters.

I tried to put the debugger there but it is not hitting...

I did the find reference for the method

/Classes/SuppItemCreate_Purch/Methods/createLine - (27, 24)

/Tables/PurchLine/Methods/lastLineNum - (12288, 28)

it is called one place in the SuppItemCreate_Purch that too at line no 27 and it is just comparison

lineNumberManager.setLine(purchLine);

if (PurchLine::lastLineNum(purchLine.PurchId) == basePurchLine.LineNumber)

{

lineNumberManager.preUpdateLineNumber(true);

}

Rohit,

Do you have this checkbox unmarked?

Go to VS > Dynamics 365 > Options

This will let you debug the method

You can step into this method -

TradeLineNumberManager::updateLineNumberOfNewOrder(this);
