please go through this…

FieldNum function - Returns the ID number of the specified field.

int fieldNum(str tableName, str fieldName)

tableName - Table name

fieldName - fieldName

You can look at the below example :

static void fieldNumExample(Args _args)


int myInt;


myInt = fieldNum(CustTable, CashDisc);

Global::info(strfmt(“CashDisc has a field ID of %1 in the CustTable table.”, myInt));


fieldnum will return id of the field in the Table…

For ex:

Check purch table > purchid > properties > Id = 1
