Assign sales organization data in product in CRM

Hi Gurus,

I need to assign/ delete the sales organization in a product which has been downloaded from ECC in CRM. It seems that we cannot change the data in "sales and distribution tab" unless making the SET TYPE editable.

Only 3 SET TYPES in the "sales and distribution" tab can be made editable by adding them in the table CRMC_PRD_CHANGE.

CRMM_PR_SALESA, CRMM_PR_SALESG and CRMM_PR_SALESG

Does someone have any idea of how to add a sales organization in a product that comes from ECC in CRM ??

Thanks for your help,

Jeff
