I have table that looks like below (sample only, its a much larger dataset). The Mat + Plant column is the unique key; the Qty column is coming from another table joined on Mat+Plant that has mutliple records for each Mat+Plant, so every entry for Qty would be an index(match()) on the Mat+Plant key. I'll leave that out to minimize clutter. The rest of the columns are all in the same table.
| Mat + Plant | MRP Type + Lot Size | Reorder point | Qty | Plant # | MRPT + LS | Safety stock | Max. level |
| 10000031021 | NDEX | 2 | 0 | 1021 | 4 | 0 | 4 |
| 10000041021 | NDEX | 2 | 0 | 1021 | 4 | 0 | 4 |
| 10000061021 | NDEX | 2 | 0 | 1021 | 6 | 0 | 6 |
| 1000006310 | PDEX | 0 | 4 | 310 | 0 | 0 | 0 |
| 10000071021 | NDEX | 2 | 0 | 1021 | 6 | 0 | 6 |
| 10000081023 | V1HB | 1 | 0 | 1023 | 2 | 0 | 2 |
| 1000009820 | PDEX | 1 | 2 | 820 | 1 | 0 | 1 |
I'd like to have a column either through a measure or otherwise that achieved the following Excel calculation:
IF ([@[MRP Type + Lot Size]] = "PDEX", [@[Reorder Point]] - [@[Qty]],
IF([@[MRP Type + Lot Size]] = "V1EX", [@[Safety Sotck]]-[@[Qty]],
IF[@[Max. level]]>0, [@[Max. level]]-[@[Qty]],0)))
I have used the following DAX formula to get me mostly there, but can't seem to use the calcualted column I generated with it to substract the Qty value from it:
MRPT + LS = IF('MRP - Master'[MRP Type + Lot Size]="PDEX",VALUE('MRP - Master'[Reorder point]),IF('MRP - Master'[MRP Type + Lot Size]="V1EX",'MRP - Master'[Safety stock],IF('MRP - Master'[Max. level]>0,'MRP - Master'[Max. level],0)))
