Information about the method parameters is missing for the interface(ABAP interface, request message ReplenishmentOrderNotification, request message namespace )

Hello Experts,

We have a system SAP SCM 5.0 and PI 7.0. We recently upgraded our SCM system from 5.0 to 7.0 EHP3.

After that whenever we are sending idocs from ECC to SCM by using PI ... we are getting the below error and moving further.

<SAP:Stack>Information about the method parameters is missing for the interface /SCA/II_BIF_REPLORDER_IN (ABAP interface, request message ReplenishmentOrderNotification, request message namespace ) </SAP:Stack>

<SAP:Retry>M</SAP:Retry>

We tried to regenerate the proxy but it also not happening by giving the error unable find software component version for name space http://sap.com/xi/SNC/Global.

Please check the attachment and provide your suggestions.

Regards,

KK
