18. HOW TO PRODUCE A STAGED BOM FOR STAGED DESIGNS

[jovivier]

There may be several reasons for wishing to produce a staged Bill Of Materials. Possibly the whole system was designed initially but only the first stage will be installed this year or you are adding on to an existing system.

Previous to IRRICAD Pro 9.5 you would highlight and delete the sections not required for the bill of materials. "Scope" was introduced to the component dialogs to specify the options Design + BOM, Design Only or BOM Only. The Design Only option is very useful for staged Bill of Materials.

Scenario #1 - Adding on to an existing system:-
In this scenario part of the system is already installed and the next stage has not been designed. Before adding on to an existing system select the entire plan and use Change to change the "Scope" to the Design Only option so these items will no longer appear in the Bill of Materials reports. Now add the new part of the system. The new components will automatically be Design + BOM by default, meaning they will be included in Design and appear in the Bill of Materials reports. If Fitting Selection is used, the connection between the old and the new will be selected if required.

Scenario #2 - A two-stage design:-
The two stage design has two scenarios - cost Stage 1 only or cost Stage 2 only. In either option, the Select|Lasso is required to careful lasso and highlight the components in the stage not required for this bill of materials report. When selected, use Change to change the "Scope" from Design + BOM to the Design Only option. If Fitting Selection is used, the connection between stage 1 and stage 2 will be selected if required. Only the unchanged stage will appear in the Bill of Materials reports.

Tips:
Note DO NOT use Change Type as many different types of items will be selected and all need to be changed in one action.

BOM Only is used for items such as flushing manifolds on tape blocks, automatically placed using the Tape Irrigation Block tool. Note that the flushing manifold automatically placed for a Spray Irrigation Block is also BOM Only however this can be changed by lassoing the flushing manifold and changing the "Scope" to Design + BOM, if you wish to size or analyse the flushing manifold. To size the flushing manifold on the sprayline design only Velocity Design can be used.
