Material Item Catagory Default

Hi,

SD guys can i get some help from your end...

When the material master records were created for AC45 the default item category on a sales order was TAN

Some material master records, for example 1142920 / 1142921 / 1142931, which were created later, have a default item category of TAB on the sales order – which is causing problems as this is not always being changed.

Can all default item categories for AC45 material master codes not used by any other plant be set with a default of TAN.

Can you assisst me how to set the default setting...

Awaiting for your kind reponse..

Best regards

Ram
