Conversion / Output not possible anymore when using JSAPCLI / CE-F

Description
The problem can occur when using JSAPCLI and/or CE-F.

When using JSAPCLI the message is as follows:
"No authorization for function RFC_METADATA_GET. (CLASS: seal.sap.sapcli.JSAPcli METHOD: sendSevere)"

With CE-the following message is logged:
"2021-07-23T12:11:20,240 [E] de.sealsystems.dpf.sapretriever.SapRetrieverApplication$ApplicationException: de.sealsystems.dpf.sapretriever.client.SapRetrieverException: com.sap.conn.jco.JCoException: (104) JCO_ERROR_SYSTEM_FAILURE: No RFC authorization for function module RFC_METADATA_GET. (Remote shortdump: RFC_NO_AUTHORITY in system [AT1|SAPCI00AT1|00])"

Cause
The process lacks authorizations.

Solution
From JAVA SAPCLI 2.1.additionally to the authorization object S_RFC the function groups
    /SEAL/BAS_CR_RFCU
    RFC_METADATA
are needed. These functions have to be added in the authrization role.
A template for these roles (_SEAL_ROLE_EXT_RFC.zip) can be requested from the SEAL Support. Please create a Jira ticket with a reference to this FAQ.
