ALV OM - keep filter while deleting lines from ALV

Question

Dear all,
I'm using an ALV (cl_salv_table) to get a proposallist of materials and substances to be linked. When a material is linked to a substance, all lines for this material are deleted from the ALV. So far, so good.
When a user sets a filter on a certain column and links a material, the filter icon on top of the column is shown while the records are not filtered accordingly. When the user selects the column again en pushes the filter button, the value that was set in the first place, is shown.
edit : I've "solved" this problem myself by getting a list of all filters, clearing lr_filters and filling lr_filters up again from this list.I        don't think this is a very clean sollution to the problem, but it works.
How can I resolve this problem in a better way? Thanks in advance.
Cheers.
Luk
