Distribution channel not allowed for sales organization

Hello,

we´ve got the following error message in a bdoc:

"Distribution channel 45 is not allowed for sales organization O 50000002"

This appeared because we´ve edited a material in ECC with the distr. channel 45.

I´ve already checked the settings in tcode ppoma_crm for sales organization O 50000002. See the screenshot below:

Could you please help me with that issue?

Thank you in advance

Dominik
