User based restrictions in Z report

Hi,

Please guide on following;

We have a customiized z report for dispatch from factory. We want to give access of this report to all our sales representatives, restricting the view to their particular area.

The field defined is SALES DISTRICT i.e. whenever a sales representative executes the report, by default only dispatches to those Sales District authorised to him should be visible to him.

Please help me on how we can apply such restrictions.

Our ABAper says restricts are possible only for single range & not for multiple range.For Ex: only A001 to A020 is possible

A001 to A020 & B001 to B015 is not possible.

I have tried doing so by creating different variant for each user, but variant has to be selected manually by the user. If he does not selects any variant then all the dispatches are visible, on the other hand if he selects some other variant, then dispatches to those Sales District are visible.

Is their any way to automate the variants for each user so that when the report is executed, each of the user has its variant default appearing & with no authorization to change.

Please suggest me if their is any other way possible to apply this restriction.

Thanks & Regards,
