Hello Nellaiappan,
It is possible.
Use User-Exit IWO10017 - Determine external order number by customer logic
You need to give the Number logic in this include. Prior to this you need to Create the Number Range through Tcode SNRO (for running serial number).
You need to use the logic in the Exit (include ZXWOCU14) for the part of Character format by concatenating the field values Year/PlGrp/Plsection/SNRO number . Then to get the sequential running serial number (from SNRO range) you need to use Function Module 'NUMBER_GET_NEXT' . With these inputs, your ABAPer should be able to achieve.
Best of Luck
