Inventory Extraction - Issues till not Resolved!!

Question

Hi Gurus,
I have couple of questions here regarding Inventory extraction, and I will ask one by one:
1. I have a requirement to develop a report called " Stock Ledger Report " where the KPI's would be Quantity, Cost & Retail Price. The 2 KPI's Quantity & Costs are straightforward and the data for these come from MSEG-MENGE & MSEG-DMBTR respectively. Retail Price is a bit complex since it is dependent on time and my client being a retail one their prices are subjected to change according to time. This is being calculated from different tables in the R/3 side so it's pretty clear that I have to add a custom field to my extractor.
Now my Question is, to which data source should I add the custom field, will it be 2lis_03_bx or 2lis_03_bf?
2. I started the extraction sometime back for 2lis_03_bx since that has to be extracted first, but I am getting a runtime error that says:
Short Text
Too many parameters specified with PERFORM.
What happened?
In a subroutine call, there were more parameters than in the
routine definition.
Error in ABAP application program.
The current ABAP program "SAPLMCB1" had to be terminated because one of the
statements could not be executed.
This is probably due to an error in the ABAP program.
Error analysis
An exception occurred. This exception is dealt with in more detail below
. The exception, which is assigned to the class
'CX_SY_DYN_CALL_PARAM_NOT_FOUND', was neither
caught nor passed along using a RAISING clause, in the procedure "UPDATE_CALL"
"(FORM)"
Since the caller of the procedure could not have expected this exception
to occur, the running program was terminated.
The reason for the exception is:
A PERFORM was used to call the routine "F0001_UPDATE" of the program
"RMCSA278".
This routine contains 4 formal parameters, but the current call
contains 5 actual parameters.
parameters.
The first thing I did was to check for the OSS notes 315880 and 353042 that have to be installed in the R/3 system to perform the data loading. I got this from the SAP White paper, How to handle Inventory scenarios in BW.
I didn't find these notes in my R/3 system here, so I searched for these nodes in market place. The first note didn't make much sense to me where as the 2nd note was about how to activate the transaction key (PROCESSKEY).
According to what was mentioned in market place, in order to work with the Inventory extractors I have to activate the determination of the PROCESS KEY. So how do I know which PROCESS KEY corresponds to my requirement ? I could see all the process keys in the Transaction key maintainence for BW in SBIW.
My Question is if these 2 OSS notes are installed. will the issues be resolved ??...Also is it possible to proceed and resolve the above issues without istalling the 2 OSS Notes.
Thanks,
Guru.

Answer 1

Hey Brian,
Sorry I mistook your reply, am stuck with too much of work buddy, working on Inventory scenarios as well as POS DM too....your answers sounds cool. I will definitely try that once am done with the issue of running the setup tables and actually I think you suggestion would definitely work in my scenario since my client s a retail client and their prices change with time.
Can you also tell answer me with regard to my 2nd question.
Thank you so much
Guru.
