Description

This error indicates that a specified minimum length for a text input field is set to an invalid value, specifically less than zero. It commonly occurs during configuration or when custom developments define input constraints incorrectly, preventing proper data entry or system processes.

Error Message

ERR_TEXT_COMMON_INVALID_MINIMUM_INPUT_LENGTH

🔍

Known Causes

3 known causes

⚠️

Incorrect Configuration Setting

A system or application configuration parameter for a text input field's minimum length has been erroneously set to a negative number.

⚠️

Custom Development Error

A custom ABAP program, Fiori extension, or another custom development defines a text field's minimum input length as a negative value.

⚠️

Data Dictionary Inconsistency

An underlying data dictionary definition for a field's minimum length constraint might be corrupted or incorrectly updated to a negative value.

Solutions

3 solutions available

1. Adjusting Search Help Minimum Input Length medium

Configure search help parameters to allow shorter input.

1

Identify the specific search help causing the error. This often occurs when a user tries to search with fewer characters than the search help is configured to require.

2

Access Transaction SE11 (ABAP Dictionary).

3

Navigate to 'Search Helps' and enter the name of the search help causing the issue. Click 'Display'.

4

In the search help definition, locate the 'Search Help Parameter' tab. Identify the parameters that are likely triggering the minimum input length validation.

5

For the relevant parameters, check the 'Minimum Input Length' field. Reduce this value to a more practical length (e.g., 1 or 2 characters). Be cautious not to set it too low, as it might impact search performance or relevance.

6

Save the changes to the search help. You may need to activate it again.

7

Test the search functionality in the relevant SAP transaction to confirm the error is resolved. It might be necessary to clear the user's cache or restart their SAP GUI session.

2. Reviewing SAP Fiori Application Configuration advanced

Examine and modify the OData service or UI annotations for Fiori apps.

1

If the error occurs in an SAP Fiori application, identify the specific Fiori app and the field or search functionality that triggers the error.

2

Determine which OData service is being used by the Fiori app. This can typically be found in the Fiori Launchpad designer or by using the browser's developer tools (Network tab).

3

Access Transaction SEGW (Gateway Service Builder) for the relevant OData service.

4

Within the OData service definition, navigate to the entity sets and properties associated with the problematic search. Look for annotations related to input validation or search help configurations.

5

Examine the UI annotations (e.g., using `UI.FieldGroup`, `UI.LineItem`, or specific search annotations) that might be defining the minimum input length for search fields. These annotations are often defined in the service's metadata or in separate annotation files.

6

Modify the relevant annotation or OData service property to adjust the minimum input length. This might involve changing a property like `sap:min-length` or similar, or adjusting the underlying search logic in the service implementation if annotations are not directly controlling it.

7

Redeploy or activate the OData service and its annotations. Clear the Fiori cache (e.g., by running report `/UI2/INVALIDATE_GLOBAL_CACHES` or using transaction `/UI2/DELETE_CACHE_AFTER_UPGRADE`) and refresh the Fiori app.

3. Analyzing Custom ABAP Code for Search Logic advanced

Debug and adjust custom ABAP programs that implement search functionality.

1

If the error occurs within a custom SAP transaction or a custom ABAP report, identify the specific ABAP program and the point where the search is being executed.

2

Use the ABAP debugger (Transaction SE80 or SE38, then 'Execute' with debugger active) to step through the code when the search is initiated.

3

Locate the code that calls search help functions (e.g., `CALL SELECTION-SCREEN`, `CALL FUNCTION 'F4_HELP'`, or custom logic involving `GET_SEARCH_HELP`).

4

Examine the parameters being passed to these search help functions or the logic that determines the input length validation. You might find explicit checks for minimum input length.

5

Modify the ABAP code to either relax the minimum input length check or to ensure that the user's input meets the required length before triggering the search. This might involve changing conditional statements or adjusting variable assignments.

ABAP
IF strlen( lv_input_value ) < iv_min_length_required.
  MESSAGE 'Minimum input length not met.' TYPE 'E'.
ELSE.
  " Proceed with search
ENDIF.

-- 

-- Modified logic to allow shorter input:
IF strlen( lv_input_value ) < iv_min_length_required AND iv_min_length_required > 1. " Example: Allow length 1 if required is > 1
  " Potentially adjust iv_min_length_required or proceed with warning
ELSE.
  " Proceed with search
ENDIF.

6

Save and activate the modified ABAP program. Test the custom transaction or report to verify the error is resolved.
