I am trying to create a primary key column from the following data set I am importing from a text file.
| Location | Prod_CD | Month | Qty |
| BLDV | 11029 | 25569 | 2120.47 |
| BLDV | 11030 | 25569 | 15186.25 |
| BLDV | 11036 | 25569 | 3358.22 |
| BLDV | 11043 | 25569 | 1434.15 |
| BLDV | 11127 | 25569 | 1916.13 |
[Month] is a serial number corresponding to a date in 1970 but that is irrelevant to me so I have an import step that extracts just the month from from [Month] (the value is 8).
I want to use the combination of [Prod_CD], [Location], and Extract of [Month] to create a primary key. I created a custom column with the following formula:
[Prod_CD]&[Location]&[Month]
This produces an error for the entire column. The result I am looking to get is (for the first row) "12029BLDV8".
