| Lead times in Manufacturing |  |
| In ERP LN, the lead time is the time to produce an item, from the production start date till the delivery date. Lead times are used for production planning purposes in Enterprise Planning and Manufacturing. Lead time elements The lead time consists of the following lead time elements: Queue time Setup time Run time Wait time Move time Operation lead time In Manufacturing, you can define lead time elements for every routing operation. ERP LN uses the lead time elements to calculate the operation lead time. ERP LN defaults the queue time, wait time, and move time in the Routing Operations (tirou1102m000) session from the Work Centers (tirou0101m000) session. You can change the defaulted values in the Routing Operations (tirou1102m000) session. Production order lead time ERP LN calculates production-order lead times by adding up all operation lead times. If operation overlap takes place because transfer batch quantities are defined, ERP LN uses more complex calculations to determine lead times and production order planning. For more information, refer to Production order lead-times (transfer batch quantity). Note In previous versions of ERP LN, if the work center was a sub-work center that had a main work center, and the next operation was carried out on a different work center, ERP LN added the wait time of the main work center to the wait time of the sub-work center. In addition, if the operation was carried out on a different work center then the previous operation, or when it was the first operation, ERP LN added the queue time of that main work center to the queue time of the sub work center. In the current version of ERP LN, this functionality has been removed. Now, ERP LN only uses main work centers for aggregation of capacity data in Enterprise Planning, and ERP LN no longer adds up queue times and wait times from main work centers and sub-work centers.
