• Message type: E = Error

• Message class: E2 - DE Data Dictionary

• Message number: 355

• Message text: Parameter assignment cannot be fully specified

What causes this issue?

You wanted to <DS:TX.DDDOK_SHLP_TBSH>link</> a search help to a
structure field or a table. To determine how the values are passed
between the input mask and the search help, the
<DS:TX.DDDOK_SHLP_PARAMETER>interface parameters</> of the search help
must be assigned to the fields of the structure or the key fields of
the table.
The system tries to generate a proposed assignment based on parameters
that share the same domain. In this case, the system was unable to find
a suitable field for all of the interface parameters of the search
help.

System Response

The assignment remains generic for those interface parameters for which
no appropriate field could be found.

How to fix this error?

Check the assignment. You may need to assign a field from another
structure or a constant to one of the unassigned parameters.
