SAP Error Message - Details

• Message type: E = Error

• Message class: E2 - DE Data Dictionary

• Message number: 151

• Message text: No value check is carried out on the screen for this data type

What causes this issue?

You can define allowed default values for a domain for data types CHAR,
NUMC, DEC, INTi. However, the DYNP processor only checks the input
values in the mask for data types CHAR and NUMC.

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 you need a value check in the mask, use data type CHAR and NUMC.
If you need type DEC or INTi fields, you currently have to program the
value check yourself.
F4 functionality (possible entries) is supported for all data types.

• What is the cause and solution for SAP error message E2151 - No value check is carried out on the screen for this data type ?

  The SAP error message E2151, which states "No value check is carried out on the screen for this data type," typically occurs when a field in a screen (such as a selection screen or a dialog screen) is defined in a way that does not allow for value checks or validations. This can happen for various reasons, including the data type of the field or the way the field is defined in the screen layout.
  Cause:
  
  Data Type Definition: The field may be defined with a data type that does not support value checks. For example, certain data types like CHAR or STRING may not have predefined value checks.
  Screen Field Attributes: The attributes of the screen field may not be set to perform value checks. This can happen if the field is defined as an input field without any associated value checks or domain checks.
  Domain or Data Element: The domain or data element associated with the field may not have any value checks defined, which means that the system does not know what values are valid for that field.
  
  Solution:
  
  Check Field Definition: Review the field definition in the screen layout. Ensure that the field is defined with the correct data type that supports value checks.
  Define Value Checks: If the field is supposed to have specific valid values, consider defining a domain with value checks or using a data element that has a value range defined.
  Modify Screen Attributes: If necessary, modify the screen attributes to enable value checks. This can be done in the Screen Painter or by adjusting the field properties in the ABAP Dictionary.
  Use Input Validation: Implement input validation logic in the ABAP code to manually check the values entered by the user before processing them further.
  
  Related Information:
  
  ABAP Dictionary: Familiarize yourself with the ABAP Dictionary (transaction SE11) to understand how data elements and domains work.
  Screen Painter: Use the Screen Painter (transaction SE80) to modify the screen layout and field properties.
  Debugging: If you are unsure why the error is occurring, consider using the debugger to trace the program execution and see where the field is being processed.
