You are getting the error: “405 Method Not Allowed” / “Error: HTTP method GET is not supported by this URL” when you try to open an SRM-MDM Catalog.
The error cause and resolution explained in SAP Note 2979632 – HTTP method GET is not supported during catalog call.
From SRM-MDM Catalog 7.32 SP06 P39 the GET method is not supported anymore, because of security reasons (to avoid attacker to access information via GET handlers). In the latest releases the POST method is allowed only to call the catalog.
Solution
Use the POST method to call the catalog from SRM:
- Follow this path to open the webservice customizing: IMG – SAP Supplier Relationship Management – SRM Server – Master Data – Content Management – Define External Web Services.
- Double click on the web service name to open the details.
- Unflag the option “Use HTTP GET To Call Web Service” if it’s selected.
Use the POST method to call the catalog from ERP/S4HANA:
- Follow this path to open the webservice customizing: t-code OLME > Environment Data > Web Services: ID and description > Call structure
- Select the web service name of catalog to open the details
- Untick indicator “Use HTTP GET” if it is selected.
