If for example you have created a product only in one branch and need it to be available in other branches also, the easiest way to resolve this is to copy the product to other locations.
To do this, find the product in the tree in Explorer.
Right click the product >Action > Copy to Location
Select the branch you want to copy from and the branch you want to copy to, either by clicking the three dots on the right and selecting the branches from the list or by typing in the branch numbers manually. Then click OK to complete the transfer.
If you refresh the Matrix view of the product, the item will now show in the branch you copied it to.
You will also receive a notification to confirm that the transfer is complete.
