first you need to ask in which area we need to validate
In reports we use
1) AT SELECTION SCREEN ON FIELD (for single field validation),
2) AT SELECTION SCREEN (for multiple field validation)
IN MPP we use
1) Field <Field_name> Module <Module_name> (for single field validation) ,
2) CHAIN.
Field : <Field-Name1>,
<Field-Name2>,
"
"
<Field-Namen> .
Module <Module name>.
ENDCHAIN.
