| Tools planning method |  |
| The purpose of tools planning is to estimate the tools that are needed for production orders, service orders, and work orders. If a production order is planned, the required tools are determined using the routing that is linked to the item. After the tools are planned, the Estimated Tool Requirements (titrp0511m000) session checks the availability of the planned tools. The tools planning procedure is used in the following sessions: Plan Tools Globally (titrp0211m000) session. The method is only used if the tool serial number is not specified. Replan Tools (titrp1202m000) session. Availability Check for Tools (titrp0213m000) session. This method is only used if the tool serial number is not specified. The tools planning method takes into account the Tools Usage field in the Tools by Tool Type (titrp0502m000) session. The number of tools to be planned is determined by the Maximum Number of Tools to be planned. When ERP LN plans tools with the Plan Tools Globally (titrp0211m000) session and with the Replan Tools (titrp1202m000) session, ERP LN considers the alternative tool types. ERP LN also takes into account the Planning Method field in the Tool Types (titrp0101s000) session. Depending on the value of this field, ERP LN uses the following methods when planning: Least Remaining Tool Life. ERP LN first considers tools with the least remaining life. Maximum Remaining Tool Life. ERP LN selects tools with the maximum remaining tool life. Based on Order Quantity. For the planning, ERP LN selects tools with a remaining tool life equal to or greater than the requirement considered for the planning. Not Applicable. The planning method is not applicable, which means the tool life is not applicable. The tools planning method procedure considers all the previously-mentioned input and plans the tools. If the requirement cannot be satisfied in one check-availability procedure, a purchase quantity is recommended. If ERP LN fails to plan the tools for the requirement, the requirement is not changed. |
