Hi experts,
after upgrading our ERP systems to EHP7, we are faced with a strange error. When we start an arbitrary transaction via SAPGUI for HTML within our Portal (7.4), a popup appears and shows the following message:
"The standards mode is not supported for documents less than 8 (Note 1674501)".
When i click on the single button "Ignore", the transaction is started with massive layout problems. Interestingly this problem is NOT caused, when i start the transaction without portal via sap/bc/gui/sap/its/webgui.
So this wrong behavior seems to be caused by the combination of SAP NetWeaver Portal AND SAPGUI for HTML. We are getting this error with IE9 and IE11, Chrome and FF have no problems.
As Note 1674501 mentioned, the compatibility mode of Internet Explorer could be an issue. Because the WebGUI is generated. i see currently no possibility to add additional meta-tags (e.g. <meta http-equiv="X-UA-Compatible" content="IE=edge" />) to the source-code of Web-Transactions.
Any ideas, how to solve this problem?
Regards Michael
