Restriction in F4 Help

Hi,

I created a variable ZVAR on infoobject 0FUND.

When I execute a query and choose F4 help on this variable ZVAR, all hierarchies on the infoobject 0FUND are shown. Here, we must be able to restrict this list of hierarchies according to a rule.

When I use F4 help, it should show only hierarchies where the first 3 char of the hierarchy tech name has 'ABC' (For example).

Can you suggest a BAPI/METHOD/FM that we can use for the above restriction.

Regards
