MRP > Merge
With a collective production order several different assemblies can be combined into one work order. This simplifies and shortens the creation of work orders, the cost analysis is restricted to the complete work order.
Conditions for merging
The structure of the work sequences must be the same, the work sequence numbers with the appropriate resources must match. Job times may differ. These are summed as fixed times (time per=0 ) and entered. As setup time ,the largest set-up time of all assemblies is used. Only from Beas 8.8 the phantom assemblies can be used. Routing position numbers need to be unique, because they are not re-numbered. Position numbers in operation sequences of sub-assemblies may not overlap with the position numbers of the superordinate assembly. If this happens, existing entries are overwritten and times are summed up.
The production order is created here as follows:
First position: In the first assembly position no assembly is stored, but all the accumulated work sequences and bills of material items. All time receipt and material reports are submitted to this position.
Following positions: Each item, which was chosen for the collective work order is inserted as a separate item. These assemblies have no BOM items and no routing. To these position the postings of the assemblies are made.
Pos 10 1x C001
Op. sequ. 20 Resource 2000 5 mins setup time, 1 min job time
Pos 10 1x C001
After merging there are the following positions:
Document-Pos 10: Collective order with BOM and routing
Document-Pos 20: Assembly 1 without BOM and routing
Document-Pos 30: Assembly 2 without BOM and routing
Document-Pos 10 – Collective order – has the following BOM
Pos 10 2x C001
Pos 30 1x C003
Op.sequ 10 Resource 1000 15 mins setup time, 15 mins job time (entered fix)
Op.sequ. 20 Resource 2000 5 mins setup time, 1 min job time
1. In retrospect it is not possible to identify what costs are incurred for which assembly. A post-calculation is possible only for the complete work order. "Like manual posting" needs to be selected as valuation method.
2. The collective production function is only available when evaluation is performed at standard price or price list. If for evaluation some kind of "evaluation price" (post calculation price) is set, this function will be hidden. The production lot size is not taken into account.
3. Batch or serial number tracing is possible only to a limited extend.
If in Configuration wizard – Production – Valuation and posting of assembly – Valuation anything else than "like manual posting" was set up, a special production type is required for this work order, as any other valuation method is not supported. See Administration – Definition – Production – Production type – Valuation
