Hi @Audrey,
thanks for reaching out!
Generally, you can apply two filters which are independent from each other by simply stating the two filters after each other, with a semicolon after each FILTER e.g.:

FILTER XYZ1;
FILTER ZYZ2;

-> both filters will be applied.
However in your example, the first filter is using EKKO.EKGRP != 995 and the second one EKKO.EKGRP = 995. If we would simply list the two filter statements after each other, we would end up with an empty table.
Thus, we have to use a CASE WHEN construct as the following:

FILTER
(
CASE WHEN
(EKKO.BSART IN (ZNB , Z3P, ZTR, ZRS) AND EKKO.EKGRP != 995)
THEN 1.0
WHEN
(EKKO.BSART IN (ZST , Z3P, ZTR, ZRS) AND EKKO.EKGRP = 995)
THEN 1.0
ELSE 0.0
END
) = 1.0

This way, the FILTER statement will filter for all cases for which either one of the two constraints (followed by THEN 1.0) applies.
Feel free to copy the statement above into your analysis.
