11.2.4 Message in Data Block
Please note the following for direct access to DBs (e.g. using an OP).
If data errors/machine data errors/traversing program errors are detected
when the parameters are written to the data block (e.g. in the parameteriza-
tion tool), an error message is stored in the data block. The error-specifica-
tion is stored in the form of an error number in the corresponding data block
(see Error List in Table 11-8
)
. The error message occurs each time the data
block is written to until the cause has been eliminated.
We recommend scanning the error message after every write operation.
