Hi ABAP Gurus,

I have a requirement as In a month I,e 01.01.2007 to 31.01.2007 I have data like First Name Last Name Father’s Name Date of Birth For Example Condition

1) If a person gets married that person’s name gets changed.

2) or else any change in that particular month.

I need to capture that changed date in that particular month.

How to capture that changed date in that particular month?

Thank you
