Cause
Decimal notation of the value for those fields like “component quantity” and “Component Scrap in Percent” in the migration template is not the same of definition in the user setting of the customer.
Resolution
When filling the fields that are in date format or numbers with decimals, make sure that your user settings are the same to the format used in the template.
Accordingly with the following information from Material BOM documentation.
Quantity Fields on Header and Item Level
If your quantity contains decimals, do not copy and paste values from another Excel file into these fields, because Excel will corrupt the data type of these fields. This in turn would cause the wrong numbers to be migrated to the system. Even the Copy value only functionality in Excel will corrupt the data type.
There are three possible options to fill the quantity fields:
-
Enter the data manually into the downloaded migration template.
-
Enter the values into a text file (for example, use the Notepad app). Copy the values from there, and use Paste special to paste the values into the column of the migration template as Text or Unicode Text.
-
Format all cells in the source Excel file as Text and use Copy values only to copy the values into the migration template.
Before uploading the XML file to the Migration Cockpit, check that the data type of these fields was not changed from String to Number.
How to check your user settings:
Go to Maintain Business User app and check Regional settings format.
Fill the template accordingly with the definition in the user settings.
