Summary :
The new ABAP Editor introduced with SAP GUI for Windows 6.40 patch level 10 is a significant update, replacing the deprecated sapabedit.ocx control. This control, including its associated files like sapab4edit.ocx and sapab4lex.dll, will exclusively be developed post further releases of SAP GUI 6.40. Important to note is its restriction where the editor support is confined to certain backend releases as listed in Note 930742, and it lacks compatibility with SAP GUI for Java or SAP GUI for HTML. Detailed files associated with the new editor include various .dll, .xml, .xsl, and other data files crucial for operation.
