Product Tree Error

76 Views

Hi,

We are implementing SAP Business One in a Bright Bar (steel) manufacturing company. Their

process are never predefined and hence their production process starts with a production

order of type Special (No Bill Of Material). We are using the same but after a few processes

we get the error "Product Tree Error Item already defined at higher level" while creating a

in between process production order and we cannot proceed further. Issue for Production (Row

Level) has a warehouse from where the goods are sent and at the header we define the

incoming warehouse.
