Elster LSTA with PI 7.4 - HR_DE_B2A_ELSTER_GZIP


I run the Elster LSTA Scenario with SAP HCM (Software component SAP_HRCDE 604 SP88) with SAP PI 7.4 AEX.

The constants for LSTA in View T_50BK are filled as shown in the attached document.

When sending an LSTA document using PB2A Transaction (B2A Manager), the error is that SAP HCM sends the function module HR_DE_B2A_ELSTER_GZIP to PI.

PI then answers that there is no Sender Agreement for function module HR_DE_B2A_ELSTER_GZIP which is normal, since this function module

is not part of the Elster HCM Scenario with PI anymore. The correct function module for Elster HCM Scenario with PI is now HR_DE_B2A_ELSTER_EXPORT and only this one.

When sending an LSTB document using PB2A Transaction (B2A Manager), then everything works fine including successful Elster answer.

Does anyone know what needs to be done in SAP HCM so that the correct function module is sent to PI when sending LSTA documents ?

Many thanks, Karim Azzedine.

The error lies in SAP documentation. In the documentation it is written that the constant ST/LSTA/SIGSW can remain empty. This is not the truth.

The constant ST/LSTA/SIGSW must be filled with the same value as constant ST/LSTB/SIGSW.

If the constant ST/LSTA/SIGSW is left empty then SAP HCM sends the HR_DE_B2A_ELSTER_GZIP function module, which produces the senderAgreement not found error in PI.

Please always fill the ST/LSTA/SIGSW with a value.

Many thanks, Karim Azzedine.
