This whitepaper will help to know the next or the previous working day based on calendar.

The calender may be the Ship to Calender or any.

SAP provided Function Module " DATE_CONVERT_TO_FACTORYDATE " can be used to know the next or the previous working day based on the Calender ID. Its also RFC enabled.

The " Correct Option " means if we are looking + or - side. + means the next working day and - means the previous working day.

The date format as the server format. And the Factory Calendar Id is the place where we can insert the Calender ID.

The FM doesn't take any default ID.

For Example :

If we want in sales order the confirm date to be overwrite and should not fall in holiday of Sip to Calender.
We can do this by writing a code in MV45AFZZ in VBEP section.
