To solve the problem, you need to edit the SY01402 table. Filter the table so that it shows you records where the syDefaultType field is equal to 70. This is the Remembered Company entry. The value in the SYUSERDFSTR field refers to the COMPANYID of the ‘remembered’ company. The only thing you need to do is either delete the record or change the value in the SYUSERDFSTR field to a company ID that exists. You can find valid company IDs in the SY01500 table in the DYNAMICS database.
Until next time, Live the Dream!
