Row matching is the process where the ingestion mechanism matches the ad spend rows reported by ingestion with attribution data recorded in the Dashboard. This is done using all dimensions available in the file’s schema, such as media source, campaign, adset, ad, etc. If they all match, the rows are designated as is-matching=TRUE. 

Names vs IDs

Ad Spend Ingestion identifies a dimension, such as campaign, adset, or ad by its name, without the ID. Currently, Ad Spend Ingestion doesn't support spend reporting using just IDs.

Note: Irrespective of the matching status, the spend is recorded.

The percentage of matched rows displays on the ingest page.

If unmatched rows are unexpected, download the unmatched report to investigate the cause. If necessary, cancel the ingestion by reverting it.

The Unmatched report contains a column, is-matched, which can have a value of TRUE (matched) or FALSE (unmatched) rows.

Previously ingested ad spend can be overwritten by using CSV files that contain data with the identical key of data previously ingested.

The key is formed from the date, media source, and campaign fields. If the keys match, data ingested last overwrites data previously ingested.

The following examples illustrates ad spend overwrite.

The following table lists all possible Ad Spend Ingestion error messages and corresponding solutions. 

Symptom 1: Cost data does not display after successful ingestion

1. In the dashboard, check to see if the campaign name displays more than once.
2. If so, locate the row where the campaign ID is blank.
   The row with the blank campaign ID contains the cost. 

Symptom 2: The ingested cost displays in a separate (additional row) without performance (installs) data. The campaign ID in the row is blank.

Cause: When both campaign ID and campaign name exist in attribution data, the CSV must contain both in order for AppsFlyer to correctly to match the cost data and avoid separate line items.

When using Excel/Google sheets to create a CSV file, the date and spend columns need to be formatted correctly before you save the file as a CSV file. Use the following procedures to format the date and spend fields correctly. 

After saving the CSV file, verify that the content is formatted correctly. Note: Don't use Excel to do the verification, rather use an editor. 

Formatting date cells in Excel

To format date cells in Excel with the format YYYY-MM-DD:

1. Select the cells to be formatted.
2. Right-click, select Format cells.
   The format cells window opens.
   

   

3. Select Custom.
4. In the Type field, enter YYYY-MM-DD
5. Click OK.
   The date is formatted.

Formatting Spend cells in Excel

Excel usually formats value cells with a comma to separate the thousands, as shown in the figure. This format is not suitable for Ad Spend Ingestion files. 

You can correct this by formatting the cells in Excel. 

To format the spend amounts without a 1000 separator: 

1. Select the cells to be formatted.
2. Right-click, select Format cells.
   The format cells window opens.
3. Select Number.
   

   

1. Clear Use 1000 separator (,). 
2. (Optional) Set the number of Decimal places. The default is 2. The maximum permitted is 5. 
3. Click OK.
   The cells are formatted correctly.

To examine the content of the CSV file, use an editor to view the file. 

• Windows: Notepad, Notepad++
• macOS: TextEdit

The following contains a screenshot of the example CSV file displayed in an editor. 

Editor view

Using an editor, examine the CSV file. Pay special attention to the following:

• Blank spaces: Ensure that there are no leading or trailing blank spaces before or after the commas that separate the fields. In Excel, use the @trim command to remove blank spaces. 
• Date: Ensure that the date field has the format YYYY-MM-DD. 
• Spend: Ensure that there is no comma in the spend field.
  

   

If Excel creates CSV file with a semi-colon ";" or other character as a delimiter but not a comma:

• This occurs when your computer's regional settings are set to a language/region that is not English.
• This issue is particularly prevalent when German is selected in the regional settings.
• The solution differs depending on your computer operating system (macOS or Windows).
• To resolve this issue, search for the latest guidance from Microsoft or other forums to revolve. Use the following search terms: Operating system (macOS or Windows) Excel change delimiter for CSV files.
