MATMAS with Z extensions and filter values

Hi,

I have extended message MATMAS with Z Extension. When the data is sent to destination using BD10 there are several segments with Plant is created in the target.

The customer requirement is to filter the data based on plant (werks). I put the filter in the distribution model for plant = xxxx.

After putting the filter I get the error Segment 'xxxx' does not exist for message type MATMAS.

The error goes away, when the filter is removed.

Do anybody how to implement filter?

Your help is appreciated.

Thank you

William
