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,

You will find most tables which have a LineNumber column contains method LastLineNum, you will have a similar implementation in all tables.

You need to do the exactly same for your your custom table.

Hi Rohit,

The simplest way is overriding the insert method on your line table and initialize the line number before super.

Check the example in PurchRFQCaseLine.Insert and line

this.LineNum = PurchRFQCaseLine::lastLineNum(this.rfqCaseId) 1.0;

Rohit,

You can check Data entities\SalesOrderLineV2Entity\insertEntityDataSource() method as well. This code sets the line number -

salesLine.LineNum = salesLine.LineNum ? salesLine.LineNum : SalesLine::lastLineNum(this.SalesOrderNumber) 1;

I am not sure. I think it is using the same class as it has the same structure.

You can debug to be sure.

You can step into this method -

TradeLineNumberManager::updateLineNumberOfNewOrder(this);
