How To Fix RSMPC134 - Loading process '&1' is not a 'Load Only PSA' type, but in PSA proc. '&3'

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'.

• What is the cause and solution for SAP error message RSMPC134 - Loading process '&1' is not a 'Load Only PSA' type, but in PSA proc. '&3' ?

  The SAP error message RSMPC134 indicates that there is a mismatch in the configuration of the loading process for a DataSource in the context of the SAP Data Warehousing environment, specifically when dealing with the Persistent Staging Area (PSA). This error typically arises when the system expects a "Load Only PSA" type process, but the current loading process does not meet that requirement.
  Cause:
  
  Incorrect Process Type: The loading process defined for the DataSource is not set to "Load Only PSA". This can happen if the DataSource is configured to load data into a different type of target (like a DataStore Object or InfoCube) instead of just the PSA.
  Configuration Issues: There may be issues in the configuration of the DataSource or the InfoPackage that is trying to load data into the PSA.
  DataSource Settings: The DataSource might be incorrectly set up to load data into a target that is not compatible with the expected PSA loading process.
  
  Solution:
  
  
  Check DataSource Configuration:
  
  Go to the DataSource in the SAP BW system and verify its settings. Ensure that it is configured to load data into the PSA.
  If the DataSource is intended to load data into a different target, you may need to adjust the InfoPackage settings accordingly.
  
  
  
  Adjust InfoPackage Settings:
  
  Open the InfoPackage associated with the DataSource and check the target settings. Ensure that it is set to load data into the PSA.
  If the InfoPackage is set to load data into a DataStore Object or InfoCube, change it to load into the PSA if that is the intended behavior.
  
  
  
  Review Process Chains:
  
  If this error occurs within a process chain, review the process chain configuration to ensure that the loading process is correctly defined and that it matches the expected type.
  
  
  
  Recreate the InfoPackage:
  
  If the issue persists, consider recreating the InfoPackage to ensure that all settings are correctly applied.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific DataSource and loading processes for additional guidance.
  
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide additional troubleshooting steps.
  Transaction Codes: Use transaction codes like RSA1 (Data Warehousing Workbench) to access DataSource and InfoPackage settings.
  Logs and Traces: Review logs and traces for more detailed error messages that might provide additional context for the issue.
  
  By following these steps, you should be able to resolve the RSMPC134 error and ensure that your loading process is correctly configured for the intended target.
