Hi @lumbera_darwin , thank you very much for your time and you suggestions.
Well, the thing is a little bit more complicated since I have 4 filter families and each family has 3 types of filtration materials, so:
1) 10 mc/h filter "A"
2) 14 mc/h filter "B"
3)22 mc/h filter "C"
4) 35 mc/h filted "D"
1) could have the following filter materials:
- 100 Kg of sabbia (0,4-0,8 micron)
- or 80 Kg of vetro
- or 100 Kg of fibalon*
2) could have the following filter materials:
- 150 Kg of sabbia (0,4-0,8 micron)
- or 120 Kg of vetro
- or 150 Kg of fibalon*
3) could have the following filter materials
- 200 Kg of sabbia (0,4-0,8 micron) + 50 Kg of sabbia (1-2 micron)
- or 120 Kg of vetro
- or 250 Kg of fibalon*
4) could have the following filter materials
- 360 Kg of sabbia (0,4-0,8 micron) + 90 Kg of sabbia (1-2 micron)
- or 360 Kg of vetro
- or 450 Kg of fibalon*
*Please note that only in case the filter material type is "fibalon" I need to add 4 more components (2 "griglia per diffusore filtro a masse" + 2 "racc. incoll passaggio per diffusore filtro a masse Ø50"(for filter 1) and 2)) or 2 "racc. incoll passaggio per diffusore filtro a masse Ø63"(for filter 3) and 4)).
So the problem is that I could have a mix of those filter into my project, but also just one or more of the same type.
In case I have a mix of them the schedule included all the parameters, even if there could be a lot of 0 is kinda ok; but in case of a project with just one or more filter of the same type I would have to edit the schedule and remove the parameters (columns) showing 0.
And if possible I would like to adopt a schedule template where I do not have to go for each project and customize it, in order to improve the efficiency.
