If you see this error message:
Many of our customers integrate L2L Spares with their ERP System. In these cases, Spares Imports are performed daily using data extracted from that ERP System. Most of the people who perform these daily uploads have created and saved a template (Mapped Table Fields) which they use day in and day out.
Saved templates are available from the drop down under Step 4: Map Table Fields to Columns. This is why they are referred to as Saved Table Mapping Field Templates. There is nothing inherently wrong with this practice and we don't discourage it.
However, and here comes the disclaimer, importing Spares should always be approached with caution. Spares Imports are not plug and play. One misstep can wipe out all of your spares data. We always advise customers to first export all current spares and retain that file, separate from, and in addition to, the file they are uploading, prior to performing a spares upload. We strongly recommend this as a Best Practice. (Because one misstep can wipe out all of your spares data when performing a Spares Full Sync upload. This is so important, it bears repeating.)
One constant about software is that it is always changing. For this reason alone, the importer should be knowledgeable about the subject matter. While you may perform this type of upload practically every day, you cannot approach this casually.
You may encounter error messages on occasion. Some of them are easily decipherable, i.e. an easy to understand message such as, 'Cost Center --ABC 123-- does not exist'. These are also easy to resolve: just create a Cost Center in your site and away you go.
The following are the most frequent causes of error messages during Spares Imports:
- The Table Mapping Fields are not mapped correctly
- Something has changed so your saved Table Mapping Field Template is no longer accurate
- Columns have been added/removed/renamed on your import file
- Column Headers have been added/removed/renamed on your import file
- The file, formatting, or data from your ERP import file has been modified
- The Import Tool itself has been modified by L2L (while this happens extremely infrequently, it is always a possibility)
For the reasons cited above, it is critical that you understand how the Column Headers from the file you are importing correlate to the individual Table Field selections to which you 'map' when creating your Table Mapping Field Templates, i.e. the options available to select from the drop down of each line item. When you have a clear understanding of these Table Field + Column relationships, error messages are no match for you!
Below you will find the following:
# 1 - Screenshot of sample Saved Table Mapping Fields. These are named and then saved using the floppy disk icon immediately to the right when performing Step 4.
# 2 - 'Select Worksheet': used if you are importing a file with multiple tabs. The Column Headers are displayed along with the top 3 rows of the worksheet to ensure you are loading the correct tab.
# 3 - This screenshot depicts all of the line items to be 'mapped' in the Table Fields and their corresponding Column (Headers).
# 4 - Screenshot of individual Table Field drop down selections
# 5 - Column Headers defined for all spares exports from L2L.
Screenshot # 1: Illustration of previously saved Table Mapping Field options available for selection:
Screenshot # 2: - Step 1: Select Worksheet (showing top 3 rows [of the file you are importing])
Note that every Column Header in the import file has a corresponding Column Header reflected in the display of the 'top 3 rows'. Please also note that these are not in the same order, hence the mapping requirement.
Step 3, Describe the Items to Import and Select the Table to import these items into, requires "Spares Full Sync" when you are performing a daily spares import. Note the warning as well: *Spares Full Sync will remove all locations and vendors not contained in the upload file.
Screenshot # 3: - This screenshot depicts all of the line items to be 'mapped' in the Table Fields and their corresponding Column (Headers). In this example, the majority of Table Fields to be mapped directly correlate with their Column Header counterparts.
*Note that this will not always be the case. The import file from your ERP system may have varying nomenclature. For example, when L2L refers to 'Cost', this may be referred to as 'Price', 'Pricing', etc. Your site may have specified different labels as well, making it critical that the person performing the import understands the fields they are mapping.
*Note also that you must not leave any Table Field mapping options without selecting a response from each individual drop down. Failure to map every Table Field will prevent the "DO IMPORT" button from being displayed for selection.
*Note as well that a number of the Vendor related Table Fields do not have corresponding Column Headers as shown in the export of spares from L2L. While this information is very helpful, the Vendor specific Table Fields are not required mapping to successfully import spares.
*Any Table Field that does not have a corresponding Column Header selection still requires a response. You must select either 'Empty String' or 'Null'. In general, use Empty String for those Table Fields where the expected response is numeric and use Null for those Table Fields where the expected response is text or alphanumeric. Likewise, you must check the corresponding 'Unique Values Do Not Import' box. If you do not, the "DO IMPORT" button will not be available for selection.
Screenshot # 3
Screenshot # 4: Individual Table Field drop down selections to which you map when creating your Table Mapping Field Templates. Again, the fields from both sources are not in the same order. When the names don't match exactly, you will have an easier time mapping them when you understand their meanings.
