I hope. Table should having two key fields.
One is field should be key other than mandt.
If i make one field as mandatory fields. Data will be Accepts like
ponumber i made mandatory. So, two key fields total 1)mandt 2)ponumber. now data will be save as.
ponumber value
501 20
502 30
But what i need is
ponumber value
501 20
501 20
502 30
How could i do it.
Can i create one more field ponumber1 as non key fields. now ponumber will be, Pass +1 .because key fields And ponumber1 as 501 ,501,502,503 like this.
