Scenario:- We need to update Bank statement entity data source field based on input value when we are importing the data into Dynamics 365 finance and operations.

Resolution: -

We need to write chain of commands/event handler for insertEntityDataSource entity method to achieve the same and logic should be written in pre event handler/ before next keyword.

Please find below sample code for your reference.

[ExtensionOf(dataentityviewstr(BankStatementEntity))]
final class BankStatementEntity_Extension
{
    public boolean insertEntityDataSource(DataEntityRuntimeContext _entityCtx, DataEntityDataSourceRuntimeContext _dataSourceCtx)
    {
        BankStmtISOAccountStatement bankStatement;
        boolean ret;
        
        if (_dataSourceCtx.name() == dataentitydatasourcestr(BankStatementEntity, BankStmtISOAccountStatement))
        {
            if (this.ToDateTime == utcDateTimeNull())
            {
                throw error("To date must be specified");
            }
            bankStatement = _dataSourceCtx.getBuffer() as BankStmtISOAccountStatement;
            bankStatement.AccountingDate = DateTimeUtil::date(this.ToDateTime);  
            _dataSourceCtx.setBuffer(bankStatement);
        }

        ret = next insertEntityDataSource( _entityCtx,  _dataSourceCtx);
     
        return ret;
   
    }

}
