How To Fix GH016 - Field & of table & allows lower case letters

SAP Error Message - Details

• Message type: E = Error

• Message class: GH - Help functions and tools in FI-SL

• Message number: 016

• Message text: Field & of table & allows lower case letters

What causes this issue?

Field &V1& is defined in table &V2& (perhaps also in other tables).
This field distinguishes between upper and lower case letters. If
you make an entry in lower case letters, the entry is not therefore
automatically converted into upper case letters.
In the FI-SL application, a distinction cannot be made between upper
and lower case letters in all modules. For example, when defining a
set, you can only enter upper case letters in the set lines.

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?

It is recommended that you only include fields in FI-SL tables which
do not distinguish between upper and lower case letters.
Note: the factor determining whether a field distinguishes between
upper and lower case letters is an attribute of the relevant data
element or the relevant domain.

• What is the cause and solution for SAP error message GH016 - Field & of table & allows lower case letters ?

  The SAP error message GH016 indicates that a specific field in a table is not accepting lower case letters, which is a restriction based on the field's definition in the database. This error typically arises when you attempt to enter data that includes lower case letters in a field that is defined to only accept upper case letters.
  Cause:
  
  Field Definition: The field in question is defined in the database schema to only accept upper case letters. This is common for fields that are meant to store certain types of identifiers or codes.
  Data Entry: The user is trying to input data that includes lower case letters, which violates the field's constraints.
  
  Solution:
  
  Change Input Data: Ensure that the data being entered into the field is in upper case. You can manually convert the input to upper case before entering it into the system.
  Use Upper Case Conversion: If you are using a program or script to input data, make sure to convert the strings to upper case using functions available in the programming language you are using (e.g., UPPER() in SQL).
  Check Field Properties: If you have access to the table definition, check the properties of the field to confirm its constraints. If necessary, consult with your database administrator or SAP consultant to understand if the field definition can be modified to allow lower case letters, although this is generally not recommended due to potential impacts on data integrity and application logic.
