  SAP Error Message:
  
  WXP755 Unexpected return code &1 for FB SPLITTERCONTROL_CREATE
  
  Cause
  This warning message typically occurs in SAP GUI or Web Dynpro applications when the system tries to create a splitter control (a UI element that divides a screen area into resizable panes) but receives an unexpected return code from the underlying function module or API call.
  Common causes include:
  
  Incompatible or missing GUI components: The SAP GUI or Web Dynpro runtime environment might be missing required components or patches.
  Incorrect parameters passed to the splitter control creation function: The function module SPLITTERCONTROL_CREATE expects certain parameters; if these are incorrect or incomplete, it may return an unexpected code.
  Version mismatch: The SAP kernel, GUI, or Web Dynpro components might be out of sync, causing unexpected behavior.
  Authorization or system environment issues: Sometimes, system restrictions or missing authorizations can cause the control creation to fail.
  Frontend rendering issues: Problems with the frontend rendering engine or browser (in case of Web Dynpro) can cause unexpected return codes.
  
  
  Solution
  
  
  Check SAP GUI and Web Dynpro versions:
  
  Ensure that the SAP GUI and Web Dynpro components are up to date and compatible with your SAP backend system.
  Apply the latest Support Packages and patches.

  If using Web Dynpro in a browser, clear browser cache or try a different browser.
  For SAP GUI, try reinstalling or updating the GUI.
