Few Production Support Issues:-

Production Support Errors :

1)Invalid characters while loading: When you are loading data then you may get some special characters like @#$%...e.t.c.then BW will throw an error like Invalid characters then you need to go through this RSKC transaction and enter all the Invalid chars and execute. It will store this data in RSALLOWEDCHAR table. Then reload the data. You won't get any error because now these are eligible chars done by RSKC

2) IDOC Or TRFC Error: 

We can see the following error at “Status” Screen:

Sending packages from OLTP to BW lead to errors

Diagnosis

No IDocs could be sent to the SAP BW using RFC.

System response

There are IDocs in the source system ALE outbox that did not arrive in the ALE inbox of the SAP BW.

Further analysis::

Check the TRFC log.

You can get to this log using the wizard or the menu path "Environment -> Transact. RFC -> In source system".

Removing errors:

If the TRFC is incorrect, check whether the source system is completely connected to the SAP BW. Check especially the authorizations of the background user in the source system.

Action to be taken:

If Source System connection is OK Reload the Data.

3)PROCESSING IS OVERDUE FOR PROCESSED IDOCs

Diagnosis 

IDocs were found in the ALE inbox for Source System that is not updated. 

Processing is overdue. 

Error correction: 

Attempt to process the IDocs manually. You can process the IDocs 

manually using the Wizard or by selecting the IDocs with incorrect 

status and processing them manually. 

Analysis:

After looking at all the above error messages we find that the IDocs are found in the ALE inbox for Source System that are not Updated.

Action to be taken:

We can process the IDocs manually via RSMO -> Header Tab -> Click on Process manually

4)LOCK NOT SET FOR LOADING MASTER DATA ( TEXT / ATTRIBUE / HIERARCHY )

Diagnosis 

User ALEREMOTE is preventing you from loading texts to characteristic 

0COSTCENTER . The lock was set by a master data loading process with the

request number. 

System response 

For reasons of consistency, the system cannot allow the update to continue, and it has terminated the process. 

Procedure 

Wait until the process that is causing the lock is complete. You can call transaction SM12 to display a list of the locks. 

If a process terminates, the locks that have been set by this process are reset automatically. 

Analysis:

After looking at all the above error messages we find that the user is “Locked”. 

Action to be taken:

Wait for sometime & try reloading the Master Data manually from Info-package at RSA1.

5) Flat File Loading Error
