RE: Inventory Item Requisition
Different suggestions were proposed.
In standard D365 it boils down to:
1)someone goes to the stock keeper and ask for an inventory item. Item is pulled out and charged to the Department the employee is working for, or the project or ... This would be done using a Movement journal, taking out the inventory and posting the value of that inventory to the <Offset account> and using Financial Dimensions that would represent the department, business unit, project etc. There could be an approval workflow for the inventory journal.
2) Purchase Requisition with <Replenishment> Purpose. The same purchase requisition with the same possibility for an approval workflow, the difference being that the end result (after approval) is a transfer order from the warehouse where the goods are kept in stock to the warehouse (or store) where the stock is required. Requires master planning to be configured to consider Purchase Req with replenishment purpose plus other in teh Purchasing policies.
Otherwise, you would be looking at a PowerApps or a development.
