About old product category when create a new trade promotion.

Hi, All.

Recently, we've changed a product's category in ECC, and uploaded them to CRM.

I went to the Web UI to create a new promotion.

I entered the product number there, it automatically retrieves the old product category which should not be used.

I checked the master data in CRM, it has been changed correctly.

But, when I try yo create a new trade promotion, it retrieved old category numbers.

I don't know from which part it retrieves this old category number.

Can anyone please help on this?

Thanks!
