Replenishment Workbench Does not show all parts


Our replenishment workbench only shows about 200 parts out of our 3500 sku’s the products are as far as i can see set up the same but it does not show on the replenishment workbench to move from our overflow warehouse to its primary warehouse and primary bin even though it needs filling

We have kanban set up properly one part works and one part does not show funny enough the only difference i saw was one part had MRP recalc needed true(the one that works) and the one that does not work has it has false

Any customizations done to the screen?

nope no customizations
