• Message number: 500

• Message text: Material & and Plant & are blocked: Wait loop

What causes this issue?

The program which you started in batch could not block material &V1& in
plant &V2&.

System Response

As the material may possibly already be blocked by other processing,
the program is placed in a loop. This loop can be run a maximum of ten
times. Each time it is run, the system tries once again to set the
block. On the tenth attempt, the system terminates the processing of
the material concerned.
