Why is parameter not being passed when executing a transaction from transaction launcher?

Hello All,

We would like to seek of your expertise on transaction launcher in SAP CRM.

We're currently facing an issue with one of our transactions that we cannot execute properly as parameters from CRM is not reaching our HCM system.

From CRM WebUI, transaction IQS2 (Change Notification) will be called from our HCM system upon interaction with the 'IQS2' from the navigation bar given the transaction (case) is in display mode.

Upon checking, transaction ID (case ID) is available prior leaving our CRM system.

However upon getting into our HCM system, transaction ID (case ID) was not submitted as expected.

As a result, no relevant notification data were pulled from our HCM system, hence, we're receiving below error as per our customizations.

With this, we're unable to transact with IQS2 from our CRM WebUI. Please help advise where and how passing of parameters take place for this case where a transaction is being called from a different system.

Thank you.

Best regards,

Jay Mercurio
