You can do this by following line of code:DATA(l_day) = m_date - CONV d(m_date(4) && '0101' ) + 1.Where m date is the date that needs to be input as type d. Note the format of type d is YYYYMMDD.ExampleIf the above function is not present in your system, you can use the below code using simple date subtraction.DATA: l_date TYPE d, l_jan_01 TYPE d, l_day TYPE i. l_date = “your input date in YYYYMMDD format” l_jan_01 = l_date. l_jan_01+4 = '0101'. ( sets the date to first day of year) l_day = l_date - l_jan_01 + 1.Read More

You can try using projection node as followsExampletable1 = CE_PROJECTION(:T1,["ACCT_ID","SALARY"]); table2 = CE_PROJECTION(:T2,["EMPL_ID" AS “ACCT_ID”,"ADD","ZIP","STATE"]); var_out = CE_JOIN(:table1,:table2,[“ACCT_ID”])Using Projection node, you can rename the column names. Note that EMPL_ID has been renamed to ACCT_ID
The .not() is used to select all elements except an element, which can be specified.ExampleYou can try to run the following code to learn how to use .not() with jQuery selector.Live Demo $(document).ready(function(){ $("p:not(.myclass)").css("background-color", "red"); }); Heading This is demo text.
