During posting a receive entry against purchase order I got following error for a product.
“No cost rollup is found for this item. Activate the item cost price.”
As understand there is no item cost activate in Dynamics Ax 2012 for this.
For this purpose you have to go
Product inform Management => Common=> Release products
Form list page open search and edit the required product
From detail page click on item cost fast tab strip
Click on item price.
From pending line create a new line and click on activate it
Now go to try purchase that Item there is no error.
For D365 Finance and Operations open The Cost management Fast tab form Released product detail from. and click on Item price
And setup the active cost price
