(1) Explain your problem, don't simply post "This isn't working". What were you doing when you faced the problem? What have you tried to resolve - did you look for a solution using "Search" ? Has it happened just once or several times?
(2) It's also good to get feedback when a solution is found, return to the original post to explain how it was resolved so that more people can also use the results.

The action or process of manufacturing or inventing something call fabrication there are many kinds of fabrication like steel fabrication, metal fabrication in Western Canada saskarc.com is a fabrication service provider and Equipment sales and rental. for more information you can check this http://saskarc.com/steel-fabrication/
The following is a sample schedule for two jobs I prepared under a single master schedule for simplicity as to show how spatial and consumable resources can be modeled. Neither P6 or MSP provide such functionality, you must look elsewhere, perhaps Spider Project or Aurora.
Note that while the jobs share production space there is no logic link between jobs, if any job is delayed or halted because of credit issues every time this happens if using soft/preferential links it would be a nightmare revising the links.
For many such jobs you better use Portfolio Management where every job will have a separate schedule but will be resource leveled on a portfolio of shared schedules and resources. As soon as a job is finished then you detach it from the portfolio keeping active only those still unfinished.
SCHEDULING OF TASKS
If your jobs can be put on hold because of lack of fabrication materials you need to consider consumable resources that cannot be modeled as if regular resources.
Material Requirements Planning (MRP) is a computer-based production planning and inventory control system. MRP is concerned with both production scheduling and inventory control. It is a material control system that attempts to keep adequate inventory levels to assure that required materials are available when needed.
Materials Requirement Planning (MRP) is not just given a schedule what I need; you also got to consider the other side, what happens if the required materials are not in time, what shall I do? It is not unusual that because of delivery limitations you have to plan for materials deliveries not as per an ideal world.
If your jobs can be put on hold because of lack of fabrication space you need to consider spatial resources, again these resources cannot be modeled using regular resource types.
You can try modeling such jobs using artificial links to move your jobs among one/multiple production areas and hand splitting of activities until consumable materials become available. Keep in mind this can be difficult for a single job, now imagine hundreds of jobs with changing conditions every day that might require hand changing all the logic.

Frequency and methodology for schedule updating is another important consideration. Because I do 100% construction jobs our approach is simple, we use default scheduling option.
COST ACCOUNTING
A practical approach can be:
Instead of using a single Jack of all Trades I prefer to follow Best of Breed approach. For Scheduling I use Spider Project, for Accounting I rather use SAP or SAGE even when both of the last two have a Scheduling Module [by far none the best scheduling tool].
Good Luck,
