SAP Error Message - Details

• Message type: E = Error

• Message class: RSMPC - Messages for Process Chains of Generic Processes

• Message number: 134

• Message text: Loading process '&1' is not a 'Load Only PSA' type, but in PSA proc. '&3'

What causes this issue?

InfoPackage '&V1&(&V2&)' (loading process '&V1&(&V2&)' is used in the
variant '&V3&(&V4&)' of the PSA process, but is no longer set to 'Load
PSA Only'.

System Response

There is no point in using this InfoPackage as a loading process in the
PSA process variant '&V3&(&V4&)', because this InfoPackage processes its
data in the data targets by itself, without using the PSA as a temporary
store.

How to fix this error?

Remove this load process from the variants of the PSA process
'&V3&( &V4&)' or, in InfoPackage '&V1&(&V2&)', change the load method to
'Load PSA Only'.
