KB0036 – Transaction “This function not possible”
You are attempting to run a Promenta transaction and receive the message “This function is not possible”.
You are entering the transaction – for example Promenta Analyser /PROMENTA/WFRM_ANYSR in the “transaction box”
The example below shows this error scenario

Solution
There are several solutions possible :
1] Modify the transaction to prefix with /n . For example /n/PROMENTA/WFRM_ANYSR . See image below.
2] Insert the transaction into your favourites menu
3] Add the transaction to your role menu

Explanation
This is standard SAP behaviour because the first character of “/” is a special character in SAP. For example you can run /o to open a new SAPGUI session or /n to switch transaction.
SAP allow partners such as Promenta to use a reserved namespace – for example /PROMENTA/ – for transaction codes.
This means transaction codes such as /PROMENTA/WFRM_ANYSR start with the special character /. Hence when used SAPGUI is not able to interpret the full transaction code.
