Help Me Fill PF FORM 3A - Reg

Hello HRs
I am filling FORM 3A(Revised) yearly return for PF.
I have a doubt How to fill the column number 6. i.e No.of days / period of non-contributing service (if any).
Which type of employees will come under this column.
Some of our labor have break in their service.
please help me to fill this column.

Dear Mr. Pradeep,
Any contribution of any employee not paid during the return period, due to temporary break of service, then mention the break period days for which you didn't deposited contribution in Col.-6 of FORM -3A (R). As example, suppose Mr. X's contribution deposited regularly within Return Period (March paid in April - Feb. paid in March) except July then mention total wages days of July in Col.-6.
