Error signalsError signals are item signals that indicate errors occurring during a planning run. Some errors are relatively easy to solve, for example, by supplying a default value or parameter where LN expects one. In other cases, however, the error can be of a more serious nature, and can lead to failure of the planning as a whole. Fatal Error A fatal error occurred. A message is given to specify the fatal error. Examples of a fatal error:
In most cases the session that started the signal generation will be aborted. If any planning has been generated, it can probably not be trusted. This signal is not related to a specific item. RPT Planning Failure While trying to generate orders for repetitive items, no default order quantity could be found. The default order quantity for repetitive items is calculated in Manufacturing, on the basis of:
No Supplying Relationship While trying to generate a planned distribution order, LN could not find any supplying relationships for the item involved. As a result, no planned distribution order is generated. You can define supplying relationships for a plan item in the Supplying Relationships (cprpd7130m000) session. No Supplying Business Partner While trying to generate a planned purchase order, LN could not find any suppliers for the item involved. However, the planned purchase order is still generated. You can define suppliers for a plan item in the Item - Purchase (tdipu0101m000) session. Item Error An item-specific error occurred. The nature of the error is specified in the signal. In most cases the error is such that the planning for the specified item has failed and cannot be trusted. Item planned after last allowed order date The finish date of a planned order falls after the last allowed order date. You can define a general value for the last allowed order date in the Last allowed Order Date field in the Items - Ordering (tcibd2500m000) session. You can also specify a warehouse-specific value in the Warehouse - Item (whwmd2510m000) session that applies if the item is delivered from that warehouse. No Items for Plan Unit A particular plan unit is empty, that is, no plan items have been assigned to it. To assign a plan item to a plan unit in the Items - Planning (cprpd1100m000) session, you can the plan unit in the Master Plan Unit field. This type of signal is not related to a specific item. No WLC Parameters Defined A particular item is assigned to a plan unit for which the master-planning engine is Workload Control (see the Plan Unit (cprpd6100m000) session), but the plan unit's WLC parameters have not been defined. You can define the WLC parameters in the Work Load Control Parameters (cpwlc2101m000) session. Insufficient Capacity The production plan is decreased due to insufficient free capacity on one of the resources defined in the bill of critical capacities. This type of signal is generated in the workload control (WLC) planning engine. Insufficient Materials The production plan is decreased due to a lack of one of the components specified in the bill of critical materials for a certain plan item. This type of signal is generated in the workload control (WLC) planning engine. Planning Failed Planning has failed because the required quantity could not be planned. The nature of the error is specified in the signal.
