How To update customers-list in Dev-Polarion

I. Email to Karim to get new export (maybe even formatted, if not, do these:)
II. Prepare CSV for Import 
1. Convert to ANSI to avoid having to pick 65001: Unicode (UTF-8) in superlong drop down in Excel 

2. Replace first comma (after numbers) with semi-colon to use that as separator as some customer names have commas
   ^(\d+), => $1;
(Check if there are customers with " in name that shouldn't be removed as it's part of branding; right now we have "Volta" Kraftfahrzeug-Elektrozubehör-Vertrieb where removal is okay) 

3. Import data into Excel 

4. Sort by customer ID 

5. Remove dummy/test entries:
   23 asdf
   999990    Testkunde
   999992    Fantasiekunde
   999999    Mustermann GmbH & Co.KG

6. Export as CSV (this is ANSI and includes quotes around customer names with comma)
   a. remove the quotes for Volta   

7. Replace single " with double "" (so they're escaped after we did step 8)

8. Add " at beginning and end of each name (";" => ";"" and "$"=>""$" (plus first and last line))

9. Remove leading "023202,Volocopter GmbH"

III. Update "D:\alm-repo\customers.csv" in bctalm repo

IV. Start "Customer import (update enum from csv)".

V. Manually in Monitor: <https://polarion.bct-technology.com/polarion/#/monitor>
run script "Customer import (update enum from csv)"
Polarion Admin -> Scheduler has the configuration:
  <!-- This updates the customer enum based on the customer.csv. Do this after updating customer.csv. -->
  <job cronExpression="0 15 2 * * ?" disabled="true" id="script.job" name="Customer import (update enum from csv)" scope="system">
