1. I imported the contracts successfully using the wizard.
2. I obtain all the contractid's values and load them on the CSV file in the correct column (Contract) for the import of the contract line.
3. There is only one contract line per contract.
4. Use the wizard for the import of the contract lines.
5. I ensure that the column headings (Excell Spreadsheet (CSV File)) are corresponding to the name of the fields in CRM.
6. Used then the Automatic option for the mapping on the wizard.
7. Import started and ended in error. The error is referring to the Contract Id field value which is also defined as a lookup field in the contract line entity.
8. The description of the error is:
" The lookup reference could not be resolved".
9. Thanking you in advance for your assistance and advice.
