Asset Master Data Upload
I am new to Asset Accounting while I have a potential job for mass upload of master data using transaction AS02. Focus is to convert the asset super number from an old reference to a new reference (to be determined by client), plus some other field modifications included in the request.

I would be using BAPI_FIXEDASSET_CHANGE for instance. What table/s I shall look into to explore the system requirements for this?

To make a mass change, you have two options:

1. If the change of the field can be put into an algorithm (e.g., enter XYZ as a super number for all assets in class 1234), you can use a mass change rule. You first define the mass change rule in the same way as you would define an asset substitution (IF something, THEN something else), then you go into the mass change transaction, select the right assets, the proper change rule ... and hit Execute.

2. Very often, it is easier to prepare the data in Excel and use transaction AS02 for the upload. Here, I can recommend transaction LSMW - you simulate (and record) the AS02 transaction on one fixed asset master, then follow all the steps proposed by the system (define fixed values, variables, etc.) and finally upload the Excel (.csv). System will automatically generate a batch input for all assets. It may take some time for you if you do it for the first time, but it is the best way if you would otherwise need to define complex algorithms.

So - use option 1 if you have a simple algorithm for many assets, and option 2 if "each case is different" or if you feel more comfortable in Excel than ABAP. Option 2 is simple, but of course takes some time to generate the upload and then run the batch sessions (while option 1 changes everything instantly in a matter of seconds).

I’ve read you post re mass changes of the fixed assets and also interesting in the transaction code for the mass changes.

Also I did not understand for LSMW how to simulate (record) AS02 transaction, could you pls describe more clear how to do it? Or better send the csv file as an example…

Here are the details:

I. To use mass change:

1. First, define a mass change rule in transaction OA02 (Accounting - Financial accounting - Fixed assets - Environment - Mass change rule). For each company code, you can define one rule (or a sequence of them). However, all of them will always be executed at the same time. Therefore, if you need to define different rules for different assets, you will have to do this repeatedly. Technically, this is done in the same way as AA substititution.

2. Once the rule is defined, you need to select assets for mass change. Go to transaction AR01 (Accounting - Financial accounting - Fixed assets - Environment - Worklist - Generate). Enter selection criteria like on any standard AA report, and run Execute. I cannot simulate this now on my system (we do not have AA), but it should ask what you want to do (mass change, mass retirement, etc.) and ask for a name of the worklist (write anything - e.g., Super number change). The system will show you a list of selected assets in a report format. Check it and make sure that it is correct. You may add or remove single assets from this (now cannot tell you how, but it is possible). If you are happy with the list, save it.

3. The last step is execution of the change. Go to transaction AR31 (same path as above), execute the report and if you are happy with the list (same as in step 2), press Save. System will show you a log of change (what went through, which errors occured). You are done.
