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

The basic principle for performance is that there should be minimal data transferred between application server and database.For your first question, I would suggest to select only the fields that are required. So, don’t use SELECT * in case you don’t require all the fields. But in specific scenarios, if you have multiple SELECT statements at various parts of your program querying the same table but different columns, it is advisable to use SELECT * as the output is stored in a buffer till your program execute. In that case, when you come to subsequent select, the system uses the ... Read More
