CRM Filtering delta load Materials does not work

Hi Experts!

I want to filtering data during a delta load.

I have set up a filter on Material in tables MARA(field MATNR) and WLK1 (fields FILIA, SSTAT). During the initial load filter works fine. But any new Materials that are created in R/3 are ignoring the WLK1 filter (filtered only by table MARA and field MATNR) and i receive different Materials which must be screened out.

I have checked Note 788822, tables CRMFILTAB and CRMPAROLTP in R/3 and everything looks fine.

Have somebody ideas why delta transfer is ignoring filter?

Thanks and best regards,

Pavel
