FG307 - Overview

• Message class: FG - Program Error Messages

• Message number: 307

• Message text: You cannot block all vendors

What causes this issue?

At least one vendor is blocked for master record maintenance.

System Response

The program cannot start.

How to fix this error?

The program for determining all customer/vendor links changes a large
quantity of customer/vendor master data. It is therefore necessary that
neither the master record of a customer nor of a vendor is being
maintained.
To start the program, determine which user has authorization to block a
customer or vendor (lock objects EXKNA1 and EXLFA1). Ask this person to
exit the transactions and restart the program. No other user can then
change the customer or vendor data for the duration of the program run.
