What causes this issue?

<ZH>This is only a warning. A generated version of the functional area
is always provided.</>
When generating query reports for queries with this functional area,
access to database and additional tables is optimized so that only the
fields really needed are provided (GET or SELECT with field list). This
greatly improves performance over the technique in which all the fields
of a table line are provided (GET without field list or SELECT *).
The current functional area might not contain all the information for
determining the required fields. In query reports this could mean that
required fields only contain their initial value when the reports are
processed.
<ZH>You should therefore check if one of the cases described below is
true and correct your functional area accordingly.</>
To optimize access to the database and addditionyl tables, the fields
needed to generate a query report are determined when you generate a
functional area. These can be the following fields:
Fields inserted in functional groups
Fields used to formulate WHERE conditions in assigned tables
Fields addressed in the coding of additional fields
Fields addressed in the coding at timepoints GET / GET LATE or during
record processing
The current functional area contains ABAP code for defining additional
fields or at timepoints GET / GET LATE or during record processing.
Because ABAP language elements can be used freely, you can access these
fields within such codings without explicitly specifying them (field
symbols, external perform, DO ... VARYING, ADD ... THEN ... UNTIL,
etc.).
To ensure that you generate the query report without errors, you must
be able to determine the fields accessed from each (!) piece of coding
(additional field, GET / GET LATE / record processing). This requires
that each field used is also specified in this piece of coding.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

If one of the pieces of coding contains ABAP statements that implicitly
access fields, use the FIELDS statement within the coding to ensure
that all the database, table and additional fields used are also
specified explicitly.
Example:
Table KNC1 contains fields UM01U, UM02U and UM03U with the monthly
business volume for the first three months of a year. An additional
field Q1 that should contain the business volume for the first quarter
computes the sum of these three fields using an external perform.
PERFORM QUARTAL1(pppppppp) USING Q1.
Fields KNC1-UM01U, KNC1-UM02U and KNC1-UM03U are accessed with the
common storage area for table KNC1 in the query report and in the
called program pppppppp. You cannot see in the given coding that the
specified fields are required. You therefore have to change this piece
of coding as follows:
PERFORM QUARTAL1(pppppppp) USING Q1.
FIELDS: KNC1-UM01U, KNC1-UM02U, KNC1-UM03U.
Note that you must do this separately for each piece of coding since a
piece of coding is only copied the query report if this is necessary.
It therefore has to be determined separately for each piece of coding
that requires fields.
Also note that only the fields used immediately have to be specified in
the coding.
Example
The additional fields F1 and F2 are defined with the following coding:
F1: F1 = tab-field. " tab-field is a database field
F2: F2 = F1 + 2.
Although F2 indirectly accesses tab-field , you do not have to specify
tab-field in the coding of F2 as a used field. Such indirect references
are automatically resolved when you generate the functional area. The
codings for both additional fields are correct in the present form.
In exceptions, the statement
FIELDS tab.
can be used in coding, where tab is a database table or an additional
table. This causes all fields of table tab to be provided in the query
report. Note that in this case you switch off optimized access to table
tab and thus greatly reduce performance when processing queries.

• What is the cause and solution for SAP error message AQV154 - Do all fields used have a name? (use help) ?

  The SAP error message AQV154, which states "Do all fields used have a name? (use help)," typically occurs in the context of SAP Query or SAP ABAP programming when there are issues related to field definitions in a query or report. This error indicates that one or more fields being referenced do not have a proper name assigned to them, which is necessary for the system to process the query or report correctly.
  Cause:
  
  Missing Field Names: The most common cause of this error is that one or more fields in the query or report do not have names assigned to them. This can happen if fields are created dynamically or if there are issues in the data dictionary.
  Incorrect Field References: If the query is referencing fields from a table or structure that do not exist or are incorrectly defined, this error may occur.
  Field Aliases: If you are using field aliases and they are not properly defined, it can lead to this error.
  
  Solution:
  
  
  Check Field Definitions: Go to the query or report definition and ensure that all fields used have valid names. You can do this by:
  
  Opening the query in the SAP Query tool (SQ01).
  Checking the field list and ensuring that each field has a name.
  
  
  
  Review Data Dictionary: If you are using custom fields or structures, check the data dictionary (SE11) to ensure that all fields are correctly defined and have names.
  
  
  Use Help Function: The error message suggests using the help function. You can press F1 on the error message or the relevant field to get more information about what might be causing the issue.
  
  
  Check for Aliases: If you are using aliases for fields, ensure that they are correctly defined and that the original fields exist.
  
  
  Debugging: If you are working with ABAP code, you can use the debugger to step through the code and identify where the issue is occurring.
  
  
  Consult Documentation: If you are unsure about the field definitions or how to resolve the issue, consult the SAP documentation or reach out to your SAP support team for assistance.
