Printing Shortages by Production Order
Knowing whether sufficient material is available at the moment you start working on a production order is essential. An availability check is especially useful in production environments where material supply is a bottleneck. An availability check can help you to do the following:
- To decide not to release a production order.
- To take corrective actions towards logistic personnel and suppliers before production starts.
- To prioritize orders in work centers.
The planned inventory transactions and the inventory data are the basis for the shortage report. For a production order that you want to start on a specific date, the inventory receipts and issues of the required material are taken into account. On the other hand, planned production orders that consume the same material are considered. To choose you can select the Include Projected Inventory check box, whether you only want to take the actual inventory into account or also the planned inventory receipts/issues.
If multiple production orders require the same material, the orders will use up the available material in the order of the allocation dates. Only planned inventory transactions that are very likely to occur are taken into account. The following planned inventory transactions are ignored:
- Forecasts
- Rough material requirements
- Requests for quotations
The following warehouses are taken into account:
- Normal warehouses
- Shop floor warehouses
- Consignment (not owned warehouses)
Ideally you do not have material shortages. However, shortages occur if the material supply does not go according to plan. Material shortages can be caused by the following reasons:
- Unreliable suppliers: The delivered material quantities are incorrect, the delivery dates are not right, or the material quality is insufficient.
- Production material consumption is higher than expected because of unplanned rejects.
- Unreliable material requirements planning (MRP).
Pessimistic analysis of material supply
If you expect your suppliers and/or MRP to be unreliable you can best make a pessimistic analysis of the material supply. To make a pessimistic analysis, select the following check boxes:
- Ignore Scheduled Receipts: The expected and planned material receipts.
and issues are not taken into account when analyzing the production orders' material supply. Select this check box if you expect materials to be late, or the quantities to be insufficient. Note that you must select the Include Projected Inventory check box before you can select the Ignore Scheduled Receipts check box.
- Ignore Blocked Inventory: The inventory that is blocked for inspection is not taken into account for analyzing the production orders' material supply. Select this check box if you expect the material quality to be poor.
Optimistical analysis of material supply
For a more optimistical analysis of the production orders' material supply, select the following check box:
- Print Total Warehouses in Planning Cluster: All warehouses (normal and WIP) in a cluster are checked for inventory when analyzing the material supply of the production orders.
Lots
If you are using lot control, and you want to check if inventory is available for the same lot as your item you must:
- Select the Sort by Warehouse check box.
- Clear the Print Planned Receipts check box.
- Clear the Print Total Warehouses in Planning Cluster check box.
If you use these settings and insufficient inventory of the lot item is available, the report shows the details of the inventory shortage. If you are not using lots, these settings generate a report with details for all inventory shortages.
- If you use this session to see whether planned inventory is free, this does not guarantee that you can use the inventory. The inventory might be claimed by another work center. To check this, look at the planned inventory requirements by selecting the Print Planned Receipts check box.
