i have implemented user exit COOMKS01 to add custom field in KS01 KS02 KS03 transactions.
But the problem is i have mandatory fields custom designed. but when i save the cost centre it will not ask these mandatory fields to fill up.
so i have implemented "COOMKS02" so that system automatically ask mandatory fields to fill up.
I dont know what to do in this exit "COOMKS02".
